Markman, J.
At issue here is whether the two-inch rule of MCL 691.1402a(2), which provides that a discontinuity defect of less than two inches in a sidewalk creates a rebuttable inference that the municipality maintained the sidewalk in reasonable repair, applies to sidewalks adjacent to state highways, as with the sidewalk at issue here, or only to sidewalks adjacent to county highways. The trial court concluded that the rule only applies to sidewalks adjacent to county highways and, thus, granted plaintiffs motion to strike the rule as an affirmative defense and denied defendant’s motion for summary disposition. However, the Court of Appeals reversed, holding that the rule is not limited to sidewalks that are adjacent to county highways, and remanded for further proceedings. Because we agree with the trial court that the rule only applies to sidewalks adjacent to county highways, we reverse the judgment of the Court of Appeals, reinstate the trial court’s orders, and remand to the trial court for further proceedings.
I. FACTS AND HISTORY
On December 4, 2005, plaintiff, Barbara Robinson, was walking on the brick sidewalk that is adjacent to Michigan Avenue, a state highway in Lansing, in front of the [4]*4Lansing Center. She stepped into a depressed area of the sidewalk, lost her balance, tripped on a raised and uneven area of bricks next to the depression, and fell forward. As a result, she fractured her wrist, necessitating two surgeries. It is undisputed that the raised portion of the sidewalk was less than two inches and that defendant, the city of Lansing, maintained this sidewalk.
Plaintiff sued defendant under the highway exception to governmental immunity, alleging that defendant had breached its duty under MCL 691.1402(1) to maintain the sidewalk in reasonable repair. Defendant answered, raising as an affirmative defense the two-inch rule of MCL 691.1402a(2). Before the close of discovery, defendant moved for summary disposition under MCR 2.116(C)(7) (governmental immunity), claiming that it was entitled to judgment as a matter of law because plaintiff had not rebutted the inference created by the rule that defendant had maintained the sidewalk in reasonable repair. Plaintiff responded and moved to strike the rule as an affirmative defense by arguing that the rule applies only to sidewalks adjacent to county highways and, as a result, was inapplicable. The trial court agreed with plaintiff and thus granted plaintiffs motion to strike and denied defendant’s motion for summary disposition.
Defendant appealed by right, arguing that nothing in MCL 691.1402a(2) limits its application to county highways. The Court of Appeals reversed and held that, in contrast to subsections (1) and (3), subsection (2) of MCL 691.1402a contains no language limiting its application to county highways. Robinson v City of Lansing, 282 Mich App 610, 616-618; 765 NW2d 25 (2009). It then remanded the case to the trial court to rule on the remaining issues and noted that defendant could refile its summary disposition motion.
[5]*5Plaintiff has sought leave to appeal, claiming that the Court of Appeals erred in its interpretation of MCL 691.1402a(2). This Court directed that oral argument be heard on the application for leave to appeal, 483 Mich 1134 (2009), and argument was heard on December 9, 2009.

III. ANALYSIS
A. GOVERNMENTAL IMMUNITY AND HIGHWAY EXCEPTION
In Michigan, governmental immunity was originally a common-law doctrine that protected all levels of government. However, in 1961, this Court abolished common-law governmental immunity with respect to municipalities. Williams v Detroit, 364 Mich 231; 111 NW2d 1 (1961); McDowell v State Hwy Comm’r, 365 Mich 268; 112 NW2d 491 (1961). In 1965, the Legislature reacted to Williams and McDowell by enacting the governmental tort liability act (GTLA), MCL 691.1401 et seq., restoring immunity for municipalities and preserving this protection for the state and its agencies. The GTLA provides: “Except as otherwise provided in this act, a governmental agency[1] is immune from tort [6]*6liability if the governmental agency is engaged in the exercise or discharge of a governmental function.” MCL 691.1407(1). This grant of immunity is currently subject to six statutory exceptions.2
At issue in this case is the highway exception, MCL 691.1402(1), which provides, in relevant part:
Except as otherwise provided in [MCL 691.1402a], each governmental agency having jurisdiction over a highway shall maintain the highway in reasonable repair so that it is reasonably safe and convenient for public travel.[3] A person who sustains bodily injury or damage to his or her property by reason of failure of a governmental agency to keep a highway under its jurisdiction in reasonable repair and in a condition reasonably safe and fit for travel may recover the damages suffered by him or her from the governmental agency.... The duty of the state and the county road commissions to repair and maintain highways, and the liability for that duty, extends only to the improved portion of the highway designed for vehicular travel and does not include sidewalks, trailways, crosswalks, or any other installation outside of the improved portion of the highway designed for vehicular travel.
“Highway” is defined as “a public highway, road, or street that is open for public travel and includes bridges, side[7]*7walks, trailways, crosswalks, and culverts on the highway.” MCL 691.1401(e) (emphasis added).
From these statutory provisions, we know that all governmental agencies, including the state, counties, and municipalities, have a duty to maintain highways under their jurisdiction in reasonable repair. However, we also know that the duty of state and county road commissions is limited to the “improved portion of the highway designed for vehicular travel,” which specifically “does not include sidewalks. .. .” MCL 691.1402(1). A municipality’s duty, on the other hand, is not similarly limited; rather, a municipality has a duty to maintain highways in reasonable repair and “highway” is specifically defined to include “sidewalks.” MCL 691.1402(1); MCL 691.1401(e). Thus, while MCL 691.1402(1) exempts state and county road commissions from liability for injuries resulting from defective sidewalks, municipalities are not exempt; municipalities do have a duty to maintain sidewalks in reasonable repair. Haliw v Sterling Hts, 464 Mich 297, 303; 627 NW2d 581 (2001) (“Pursuant to [MCL 691.1402(1)], the duty to maintain public sidewalks in ‘reasonable repair’ falls on local governments, including cities, villages, and townships.”); Glancy v City of Roseville, 457 Mich 580, 584; 577 NW2d 897 (1998) (“[MCL 691.1402(1)] requires municipalities to maintain sidewalks in ‘reasonable repair.’ ”); Listanski v Canton Twp,

The GTLA provides: “Except as otherwise provided in this act, a governmental agency[1] is immune from tort [6]*6liability if the governmental agency is engaged in the exercise or discharge of a governmental function.” MCL 691.1407(1). This grant of immunity is currently subject to six statutory exceptions.2
At issue in this case is the highway exception, MCL 691.1402(1), which provides, in relevant part:
Except as otherwise provided in [MCL 691.1402a], each governmental agency having jurisdiction over a highway shall maintain the highway in reasonable repair so that it is reasonably safe and convenient for public travel.[3] A person who sustains bodily injury or damage to his or her property by reason of failure of a governmental agency to keep a highway under its jurisdiction in reasonable repair and in a condition reasonably safe and fit for travel may recover the damages suffered by him or her from the governmental agency.... The duty of the state and the county road commissions to repair and maintain highways, and the liability for that duty, extends only to the improved portion of the highway designed for vehicular travel and does not include sidewalks, trailways, crosswalks, or any other installation outside of the improved portion of the highway designed for vehicular travel.
“Highway” is defined as “a public highway, road, or street that is open for public travel and includes bridges, side[7]*7walks, trailways, crosswalks, and culverts on the highway.” MCL 691.1401(e) (emphasis added).
From these statutory provisions, we know that all governmental agencies, including the state, counties, and municipalities, have a duty to maintain highways under their jurisdiction in reasonable repair. However, we also know that the duty of state and county road commissions is limited to the “improved portion of the highway designed for vehicular travel,” which specifically “does not include sidewalks. .. .” MCL 691.1402(1). A municipality’s duty, on the other hand, is not similarly limited; rather, a municipality has a duty to maintain highways in reasonable repair and “highway” is specifically defined to include “sidewalks.” MCL 691.1402(1); MCL 691.1401(e). Thus, while MCL 691.1402(1) exempts state and county road commissions from liability for injuries resulting from defective sidewalks, municipalities are not exempt; municipalities do have a duty to maintain sidewalks in reasonable repair. Haliw v Sterling Hts, 464 Mich 297, 303; 627 NW2d 581 (2001) (“Pursuant to [MCL 691.1402(1)], the duty to maintain public sidewalks in ‘reasonable repair’ falls on local governments, including cities, villages, and townships.”); Glancy v City of Roseville, 457 Mich 580, 584; 577 NW2d 897 (1998) (“[MCL 691.1402(1)] requires municipalities to maintain sidewalks in ‘reasonable repair.’ ”); Listanski v Canton Twp, 452 Mich 678, 690; 551 NW2d 98 (1996) (“[T]ownships are liable for injuries occurring on sidewalks that abut state or county roads as a result of their negligent failure to maintain their sidewalks in reasonable repair.”), citing Mason v Wayne Co Bd of Comm’rs, 447 Mich 130, 136 n 6; 523 NW2d 791 (1994) (“[T]he purpose of [the limiting sentence of MCL 691.1402(1)], which applies only to counties and the state, is to allocate responsibility for sidewalks and crosswalks to local governments, includ[8]*8ing townships, cities, and villages.”); Jones v City of Ypsilanti, 26 Mich App 574, 581; 182 NW2d 795 (1970) (holding that cities are liable for injuries occurring on sidewalks that abut state highways as a result of their negligent failure to maintain their sidewalks in reasonable repair). In other words, when MCL 691.1402(1) and MCL 691.1401(e) are read together,4 it is clear that all governmental agencies except the state and county road commissions have a duty to maintain sidewalks in reasonable repair. Indeed, in the instant case, defendant does not argue that it does not have a duty to maintain the sidewalk at issue in reasonable repair,5 but only argues that because the sidewalk’s discontinuity defect was less than 2 inches, MCL 691.1402a(2) creates a rebuttable inference that the municipality maintained the sidewalk in reasonable repair and that plaintiff has not rebutted this inference. Therefore, as the Court of Appeals recognized, the “salient question... is whether the city is entitled to assert as a defense the two-inch rule set forth in MCL 691.1402a(2).” Robinson, 282 Mich App at 615.
[9]*9B. TWO-INCH RULE
As with governmental immunity itself, the two-inch rule was originally a common-law rule.6 In Harris v Detroit, 367 Mich 526, 528; 117 NW2d 32 (1962), the [10]*10two-inch rule was described as meaning that “a depression in a walk which does not exceed 2 inches in depth will not render a municipality liable for damages incident to an accident caused by such depression.” “The basis of the two-inch rule [was] the concept of ‘reasonable repair.’ ” Glancy, 457 Mich at 586. “The two-inch rule was a bright-line rule stating that defects of two inches or less constituted ‘reasonable repair’ as a matter of law.” Id. at 586-587. In 1972, however, this Court abolished the rule, Rule v Bay City, 387 Mich 281; 195 NW2d 849 (1972),7 and, in 1998, we refused to readopt it, Glancy, 457 Mich at 582. In 1999, the Legislature took up the issue, and a statutory two-inch rule was adopted in MCL 691.1402a,8 which provides:
(1) Except as otherwise provided by this section, a municipal corporation has no duty to repair or maintain, and is not liable for injuries arising from, a portion of a county highway outside of the improved portion of the highway designed for vehicular travel, including a sidewalk, trailway, crosswalk, or other installation. This subsection does not prevent or limit a municipal corporation’s liability if both of the following are true:
(a) At least 30 days before the occurrence of the relevant injury, death, or damage, the municipal corporation knew or, in the exercise of reasonable diligence, should have known of the existence of a defect in a sidewalk, trailway, crosswalk, or other installation outside of the improved portion of the highway designed for vehicular travel.
[11]*11(b) The defect described in subdivision (a) is a proximate cause of the injury, death, or damage.
(2) A discontinuity defect of less than 2 inches creates a rebuttable inference that the municipal corporation maintained the sidewalk, trailway, crosswalk, or other installation outside of the improved portion of the highway designed for vehicular travel in reasonable repair.
(3) A municipal corporation’s liability under subsection (1) is limited by section 81131 of the natural resources and environmental protection act, 1994 PA 451, MCL 324.81131.[9]
Although the very first sentence of MCL 691.1402a(l) begins by stating that a municipality is not liable for injuries arising from a portion of a county highway outside the improved portion of the highway designed for vehicular travel, including a sidewalk, trailway, crosswalk, or other installation, this sentence is prefaced by the language “[e]xcept as otherwise provided by this section,” and the very next sentence of this subsection states that a municipality is liable for such injuries under certain circumstances. 10 That is, a municipality is [12]*12liable for injuries arising from a defective sidewalk adjacent to a county highway if (a) the municipality knew or should have known at least 30 days before the occurrence of the injury of the existence of the defect in the sidewalk and (b) that defect was a proximate cause of the injury. MCL 691.1402a(l). In addition, MCL 691.1402a(2) provides that a discontinuity defect of less than 2 inches creates a rebuttable inference that the municipality maintained the sidewalk in reasonable repair, as is required by MCL 691.1402(1); this is the statutory two-inch rule. 11
As discussed earlier, MCL 691.1402(1) imposes liability on municipalities for injuries resulting from defective sidewalks, i.e., sidewalks that the municipality has failed to maintain in reasonable repair. Haliw, 464 Mich at 303 (“Pursuant to [MCL 691.1402(1)], the duty to maintain public sidewalks in ‘reasonable repair’ falls on [13]*13local governments, including cities, villages, and townships.”). However, MCL 691.1402a limits this liability by providing that municipalities are only liable for injuries resulting from defective sidewalks adjacent to county highways under the specified circumstances. Moreover, if this defect constitutes a discontinuity of less than 2 inches, a rebuttable inference arises that the municipality maintained the sidewalk in reasonable repair, which is all that the municipality is required to do under MCL 691.1402(1). Therefore, when MCL 691.1402(1) and MCL 691.1402a are read together, it is clear that municipalities are generally liable for injuries resulting from defective sidewalks.12
While defendant contends that the rebuttable inference of MCL 691.1402a(2) applies to all cases in which a plaintiff is seeking to impose liability on a municipality for an injury resulting from a defective sidewalk, plaintiff contends that this rebuttable inference only applies in cases in which the defective sidewalk is adjacent to a county highway. For several reasons, we agree with plaintiff.
First, as discussed above, MCL 691.1402a(l) begins by stating that a municipality “is not liable for injuries arising from, a portion of a county highway . . ., including a sidewalk,” unless certain conditions are satisfied. (Emphasis added.) These conditions are then set forth in MCL 691.1402a(l)(a) and (b). Then, immediately thereafter, MCL 691.1402a(2) indicates that a discontinuity defect of less than 2 inches creates a rebuttal [14]*14inference that the municipality maintained the sidewalk in reasonable repair. Nothing in subsection (2) suggests that its scope is any different than that of subsection (1); that is, there is no language in subsection (2) that indicates that although subsection (1) only applies to county highways, subsection (2) should be construed as additionally applying to highways other than county highways, such as state or city highways.
Second, not only do the placement of subsection (2) and the absence of language in subsection (2) distinguishing it from subsection (1) suggest that subsection (2), as with subsection (1), only applies to county highways, but the syntax of subsection (2) also suggests that both these subsections apply only to county highways. Subsection (2) refers to “the highway.” (Emphasis added.) As this Court has explained:
“The” and “a” have different meanings. “The” is defined as “definite article. 1. (used, [especially] before a noun, with a specifying or particularizing effect, as opposed to the indefinite or generalizing force of the indefinite article a or an). ...” Random, House Webster’s College Dictionary, p 1382. [Massey v Mandell, 462 Mich 375, 382 n 5; 614 NW2d 70 (2000).][13]
Because subsection (2) refers to “the highway,” we must determine to which “specific or particular” highway subsection (2) refers to. That is, because subsection (2) does not refer to “a highway,” we cannot read subsection (2) as applying to highways in “general.”14 Given that subsec[15]*15tion (2) immediately follows subsection (1), which limits its application to “county highwayts],” “the highway” referred to in subsection (2) must be the same highway referred to in subsection (1) — the county highway.
Third, subsection (2) cannot be read in isolation, but must be read in context. Defendant argues, and the Court of Appeals agreed, that because the Legislature did not expressly use the word “county” in subsection (2), this word cannot be read into subsection (2). If subsection (2) were to be read in isolation, defendant and the Court of Appeals might be correct in this analysis because it is well established that “we may not read into the statute what is not within the Legislature’s intent as derived from the language of the statute.” AFSCME v Detroit, 468 Mich 388, 400; 662 NW2d 695 (2003). However, it is equally well established that to discern the Legislature’s intent, statutory provisions are not to be read in isolation; rather, context matters, and thus statutory provisions are to be read as a whole. Apsey v Mem Hosp, 477 Mich 120, 132 n 8; 730 NW2d 695 (2007) (“To discern the true intent of the Legislature, . .. statutes must be read together, and no one section should be taken in isolation.”); Griffith v State Farm Mut Automobile Ins Co, 472 Mich 521, 533; 697 NW2d 895 (2005) (“ ‘[T]he meaning of statutory language, plain or not, depends on context.’ ”) (citation omitted); G C Timmis & Co v Guardian Alarm Co, 468 Mich 416, 421; 662 NW2d 710 (2003) (“[W]ords in a statute should not be construed in the void, but should be read together to harmonize the meaning, giving effect to the act as a whole.’ ”) (citation omitted).15 [16]*16“[A]ny attempt to segregate any portion or exclude any portion [of a statute] from consideration is almost certain to distort the legislative intent.” 2A Singer & Singer, Statutes and Statutory Construction (7th ed), § 47.2, p 282. For the reasons discussed throughout this opinion, although only subsection (1) expressly refers to “county” highways, we believe that when MCL 691.1402a is read as a whole, it is clear that both subsections (1) and (2) only apply to such highways.
Fourth, the Legislature is not required to be overly repetitive in its choice of language. In essence, the issue here boils down to whether the Legislature was required to repetitively restate “county” throughout the entire statutory provision. We do not believe that this is required of the Legislature in order that it communicate its intentions. Instead, we believe that a reasonable person reading this statute would understand that all three subsections of this provision apply only to county highways. Indeed, if the Legislature had intended subsections (2) and (3) to apply to highways other than county highways, we believe that it would have been reasonably incumbent upon the Legislature to so indicate. Even subsection (1) only refers to “county highway” one time and thereafter simply refers to “the highway,” and defendant conceded at oral argument that these subsequent references to “the highway” in subsection (1) signify “county highway.” The first time [17]*17that “highway” is used in MCL 691.1402a, it is immediately preceded by the word “county”; however, the next three times that it is used, it is not preceded by the word “county.” Although defendant concedes that the second and third such references mean “county highway,” defendant argues that the fourth reference to “highway” means any highway. We respectfully disagree. Instead, we believe that the fourth reference to “highway,” just like the previous references in MCL 691.1402a, is a reference only to “county highways.” In short, we do not believe that the Legislature is under an obligation to cumbersomely repeat language that is sufficiently incorporated into a statute by the use of such terms as “the,” “such,” and “that.”16
Fifth, unless the Legislature indicates otherwise, when it repeatedly uses the same phrase in a statute, that phrase should be given the same meaning throughout the statute. Paige v Sterling Hts, 476 Mich 495, 520; 720 NW2d 219 (2006) (indicating that “absolutely identical phrases in our statutes” should have identical meanings). In MCL 691.1402a, all the references to “the highway” are encompassed within the identical phrase — “outside of the improved portion of the highway designed for vehicular travel.” Therefore, all the references to “the highway” should be interpreted in the same manner. Given that the first three references to “highway” in MCL 691.1402a indisputably refer to county highways only, we see no reason why the fourth reference to “highway” should be construed any differently.
Finally, the principle that statutory provisions should not be construed in a manner that renders language [18]*18within those provisions meaningless also supports our conclusion that the two-inch rule of MCL 691.1402a(2) only applies to sidewalks adjacent to county highways. Nat’l Pride at Work, Inc v Governor, 481 Mich 56, 70; 748 NW2d 524 (2008) (“[A]n interpretation that renders language meaningless must be avoided.”). As discussed earlier, before MCL 691.1402a was enacted in 1999, MCL 691.1402(1) already imposed liability on municipalities for injuries resulting from defective sidewalks. Haliw, 464 Mich at 303 (“Pursuant to [MCL 691.1402(1)], the duty to maintain public sidewalks in ‘reasonable repair’ falls on local governments, including cities, villages, and townships.”). Therefore, MCL 691.1402a was plainly not enacted to introduce such liability on municipalities. Instead, it was enacted to limit this liability.17 So one must ask how does MCL 691.1402a limit this liability? At first blush, it would [19]*19appear that MCL 691.1402a(l) limits this liability to instances in which (a) the municipality knew or should have known of the defect in the sidewalk at least 30 days before the injury occurred and (b) this defect was a proximate cause of the injury. However, both of these limitations also existed before the enactment of MCL 691.1402a. Indeed, both of these limitations have existed since the Legislature first enacted the GTLA in 1965.
The first of these limitations, i.e., the one set forth in MCL 691.1402a(l)(a) regarding the municipality’s knowledge of the defect, was first set forth in MCL 691.1403, which provides:
No governmental agency is liable for injuries or damages caused by defective highways unless the governmental agency knew, or in the exercise of reasonable diligence should have known, of the existence of the defect and had a reasonable time to repair the defect before the injury took place. Knowledge of the defect and time to repair the same shall be conclusively presumed when the defect existed so as to be readily apparent to an ordinarily observant person for a period of 30 days or longer before the injury took place.
As one can see, MCL 691.1402a(l)(a) and MCL 691.1403 are virtually identical; they both limit a municipality’s liability to instances in which the municipality knew or should have known of the defect at least 30 days before the injury took place.
The second of these limitations, i.e., the one set forth in MCL 691.1402a(l)(b) requiring that the defect in the sidewalk have been a proximate cause of the injury, was first set forth in MCL 691.1402(1), which provides, in pertinent part:
[20]*20A person who sustains bodily injury or damage to his or her property by reason of failure of a governmental agency to keep a highway under its jurisdiction in reasonable repair and in a condition reasonably safe and fit for travel may recover the damages suffered by him or her from the governmental agency. [Emphasis added.]
This Court has held that this language requires that the defect have been a proximate cause of the injury:
W]here a plaintiff successfully pleads in avoidance of governmental immunity, i.e., that the alleged injury occurred in a location encompassed by MCL 691.1402(1), the plaintiff must still prove, consistent with traditional negligence principles, the remaining elements of breach, causation, and damages contained within the statute. ...
Proof of causation requires both cause in fact and legal, or proximate, cause. [Haliw, 464 Mich at 304, 310.]
See also Allison v AEW Capital Mgt, LLP, 481 Mich 419, 434; 751 NW2d 8 (2008) (“To recover under MCL 691.1402(1), a plaintiff must demonstrate that a defect in the highway was [a] proximate cause of the plaintiffs injury.”).
Although it is clear that MCL 691.1402a(l) was enacted to limit the liabilities of a municipality with regard to county highways, given that the two limitations set forth in MCL 691.1402a(l)(a) and (b) existed before MCL 691.1402a was enacted and that these limitations already applied to all highways, there must be some other reason that the Legislature chose to enact MCL 691.1402a(l). We believe that this other reason was to codify the two-inch rule with respect to county highways only. That is, unless MCL 691.1402a(l) is interpreted as limiting the two-inch rule to sidewalks adjacent to county highways, it is nothing more than a [21]*21restatement of existing law in Michigan. In other words, MCL 691.1402a(l) is mere surplusage unless “county highway” in that subsection is construed to limit the application of the two-inch rule in MCL 691.1402a(2), and it is well established that “[i]n interpreting a statute, we [must] avoid a construction that would render part of the statute surplusage or nugatory.” People v McGraw, 484 Mich 120, 126; 771 NW2d 655 (2009). In light of this historical backdrop, we believe it is clear that the significance of MCL 691.1402a(1) is its limitation to county highways.18
To summarize, MCL 691.1402a(l) limits a municipality’s liability with regard to county highways, MCL 691.1402a(2) codifies the two-inch rule with regard to county highways, and MCL 691.1402a(3) limits a municipality’s liability with regard to county highways and off-road vehicles.19 In other words, subsection (1) sets [22]*22forth in clear terms the general rule regarding a municipality’s liability for defective sidewalks adjacent to county highways, subsection (2) adopts a statutory two-inch rule for those sidewalks, and subsection (3) provides an exception to liability for these same sidewalks. This establishes a fully rational and coherent legislative scheme. MCL 691.1402a does not apply to sidewalks adjacent to highways other than county highways, such as sidewalks adjacent to state highways. Therefore, the two-inch rule of MCL 691.1402a(2) does not apply to the latter.20
IV CONCLUSION
For the reasons discussed, we conclude that the two-inch rule of MCL 691.1402a(2) does not apply to sidewalks adjacent to state highways; it only applies to sidewalks adjacent to county highways. Therefore, we reverse the judgment of the Court of Appeals, reinstate the trial court’s orders granting plaintiffs motion to [23]*23strike the two-inch rule as an affirmative defense and denying defendant’s motion for summary disposition, and remand to the trial court for further proceedings.
