RIPPLE, Circuit Judge.
The plaintiffs brought this action under 42 U.S.C. § 1983, 42 U.S.C. § 1985, and Title VI of the Civil Rights Act of 1964 (42 U.S.C. § 2000d) to challenge the manner in which Indiana administers the program for minority-owned business participation required by federal statutes and regulations providing federal funding for highway construction. The plaintiffs appeal the district court’s decision to grant summary judgment in favor of the defendants as well as various evidentiary rulings made by the district court prior to its summary judgment ruling. For the reasons set forth in the following opinion, we affirm the judgment of the district court.
I
BACKGROUND
A. The Statutory Scheme
In various highway funding statutes, Congress has established participation goals for minority-owned contractors. Under the Surface Transportation Assistance . Act of 1982 (“STAA”),1 the Surface Transportation and Uniform Relocation Assistance Act of 1987 (“STURAA”),2 and the Intermodal Surface Transportation Efficiency Act of 1991 (“ISTEA”),3 each recipient of federal highway funds must expend at least 10% of such funds with small business concerns owned and controlled by socially and economically disadvantaged individuals.
The Department of Transportation (“DOT”) has promulgated regulations to implement these statutes. See 49 C.F.R. Pt. 23 (1998). These regulations require states receiving federal funds to submit to the DOT a disadvantaged business enterprise affirmative action program. See id. § 23.43(b). The regulations also establish eligibility standards that a business must meet to be certified as a disadvantaged business enterprise (“DBE”). See id. § 23.62. The governing statutes provide that Black Americans, Hispanic Americans, Native Americans, Asian Pacific Americans, and women are rebuttably pre[747]*747sumed to be “socially and economically disadvantaged.” When certifying companies as DBEs, a state may apply this presumption without investigating the situation of particular applicants. See id. § 23.69 & App. A to Subpt. D. However, the regulations allow third parties to challenge the certification of a particular business by presenting evidence to rebut the presumption of disadvantage. See id.
The statutory scheme does not provide specific goals or quotas for participation by any particular disadvantaged group but instead establishes an overall goal of DBE participation of 10% for all groups combined. See id. §§ 23.61, 23.62. The Secretary of Transportation is authorized to approve an overall goal of less than 10% if a state provides sufficient justification for a lower percentage. See id. § 23.65. The DBE requirements apply to all contracts funded in whole or in part by federal highway money. See id. § 23.43.
B. Proceedings in the District Court
The plaintiffs4 brought suit in district court, alleging that Indiana 5 has not fulfilled its responsibilities under the statutory scheme. Their primary claim is that Indiana has improperly satisfied the 10% DBE participation requirement by certifying and giving business to various “sham” or “front” companies that are not truly disadvantaged, thus diverting business from legitimate DBEs. The plaintiffs also assert that certain aspects of Indiana’s DBE program do not comply with federal requirements. In particular, the plaintiffs complain of the manner in which Indiana conducts the certification process, its failure to provide a bonding, finance, and technical assistance program, and its failure to meet the 10% DBE requirements legitimately. The plaintiffs seek relief under § 1983 for alleged violations of the federal statutes and the Fourteenth Amendment’s Equal Protection Clause, under Title VI (42 U.S.C. § 2000d) for the defendants’ allegedly discriminatory administration of a federally funded program, and under 42 U.S.C. § 1985(3) for conspiracy to violate the plaintiffs’ civil rights.
In prior stages of this litigation, the district court dismissed on Eleventh Amendment grounds all claims against the State of Indiana, INDOT, and DOA, except for the Title VI claim. The district court also dismissed all § 1983 claims for money damages against the individual state officers sued in their official capacities. The claims that remained at the summary judgment stage are (1) the § 1983 claim for prospective relief against the individual state officials for alleged violations of STURAA and ISTEA, (2) the § 1983 claim for prospective relief against the individual state officials for alleged violations of equal protection, (3) the Title VI claim against the State of Indiana, IN-DOT, DOA, and the individual defendants, and (4) the § 1985 claim against the individual defendants.
C. Holding of the District Court
In a comprehensive and thoughtful opinion, the district court addressed the par[748]*748ties’ cross motions for summary judgment.6
A.
The district court first addressed the plaintiffs’ § 1983 claim for alleged violations of STURAA, ISTEA, and the implementing regulations. Relying on the Supreme Court’s decision in Blessing v. Freestone, 520 U.S. 329, 117 S.Ct. 1353, 137 L.Ed.2d 569 (1997), the court concluded that the statutory scheme does not give rise to individual rights enforceable under § 1983. The court explained that, because the statutory scheme only prescribes a course of conduct for states to follow in structuring their DBE programs but does not confer any particular benefits on any particular individuals, the plaintiffs have no individual rights enforceable under § 1983. The court nevertheless did conclude that, under the reasoning in Mallett v. Wisconsin Division of Vocational Rehabilitation, 130 F.3d 1245, 1252-53 (7th Cir.1997), the plaintiffs could utilize § 1983 to sue for a DBE plan that complies with [749]*749federal requirements for the receipt of highway funding. The court emphasized that the plaintiffs do not, however, have an individual right to sue under § 1983 to remedy isolated violations of an otherwise compliant plan.
B.
Turning next to the plaintiffs’ § 1983 claim for a statewide plan that complies with federal requirements, the district court determined that Indiana’s program meets all federal requirements. The district court conducted a detailed review of Indiana’s DBE plan in light of the program components required under 49 C.F.R. § 23.45 and concluded that the plan satisfies the regulatory requirements. The court noted that Indiana’s plan was first approved by the Federal Highway Administration in 1983 and has been re-approved periodically since then.
The district court then addressed specifically the plaintiffs’ three arguments that Indiana’s program violates federal requirements: (1) the lack of a bonding and financial assistance program, (2) the alleged failure to conduct site visits during the certification process, and (3) the alleged failure to meet the 10% DBE goal. First, the district court concluded that there was no issue for trial on the plaintiffs’ first contention, because the federal regulations do not require a bonding program. The court explained that 49 C.F.R. § 23.41 requires states to implement a DBE plan that incorporates the elements listed in § 23.45(e) through (i), which do not include a bonding and financial assistance program. Next, the court held that the plaintiffs had not adequately shown that the defendants failed to conduct site visits, because the plaintiffs’ key witness testified only that she was unaware of any site visit to her company. Moreover, the court held, the use of post office box numbers rather than street addresses for many firms listed in the DBE directories was not probative of the state’s alleged noncompliance with the site visit requirement. Finally, the district court found no genuine issue as to the plaintiffs’ third contention— that Indiana never met the 10% DBE goal — because it was not supported by any facts. The plaintiffs’ key argument is that Indiana uses front companies to fulfill the DBE requirements. However, the plaintiffs never challenged the DBE certifications of any of these companies, as provided for in 49 C.F.R. § 23.69; nor have the plaintiffs made any showing that Indiana had any information in its possession that would rebut the presumption of these companies’ DBE eligibility. The district court therefore granted summary judgment for the defendants on this § 1983 claim.
C.
The district court then turned to the plaintiffs’ § 1983 claim for alleged violations of the Fourteenth Amendment’s Equal Protection Clause. The court first addressed the various plaintiffs’ Article III standing to bring this claim. The court determined that the Contractors Association has standing as a representative of its members, but only to seek equitable remedies. The court then held that only the two plaintiffs who own certified DBEs, Fran Scott and A1 Young, could possibly establish the first standing requirement of an injury in fact, because only they could show that they were ready, willing, and able to bid on federally funded highway contracts but that a race-based barrier impaired their ability to compete on an equal basis with other DBE contractors. However, the court held, even if these two plaintiffs could show an injury in fact, they could not demonstrate the second standing requirement of a causal connection between the defendants’ conduct and their injury. In the court’s view, the plaintiffs simply had produced no evidence of any race-based or discriminatory policy of the state, or any other barrier imposed by the state, that impeded the plaintiffs’ ability to bid on contracts relative to other certified DBEs.
[750]*750In the alternative, the court held, even if the plaintiffs had standing, their equal protection claim must fail on the merits because they have not shown that the defendants acted with discriminatory intent. The court relied on our decision in Nabozny v. Podlesny, 92 F.3d 446, 453-54 (7th Cir.1996), which made clear that liability under § 1983 for a violation of equal protection requires a showing that the defendants acted with discriminatory purpose and discriminated against the plaintiffs based on their membership in a defined class.
D.
Turning next to the plaintiffs’ Title VI claim, the district court held that, because the plaintiffs had not shown a violation of the Equal Protection Clause, they could not prove a direct claim under Title VI. As for a possible disparate impact claim, the district court found that the plaintiffs had failed to support such a claim with any evidence of a statistical disparity between the percentage of contracts awarded to African American DBEs and the percentage of DBEs qualified for highway construction work that are owned by African Americans.
E.
Finally, the district court concluded that the plaintiffs’ § 1985 claim was without merit because they had presented no admissible evidence demonstrating an express or implied agreement; nor had they established any underlying violation of federal law.
II
DISCUSSION
A. § 1983 Claim Under STURAA and ISTEA
We first address the plaintiffs’ submission that the district court erred in holding that the statutory scheme does not create individual rights enforceable through § 1983. In Blessing v. Freestone, 520 U.S. 329, 117 S.Ct. 1353, 137 L.Ed.2d 569 (1997), the Supreme Court first emphasized the governing principle: “In order to seek redress through § 1983 ... a plaintiff must assert the violation of a federal right, not merely a violation of federal law.” Id. 117 S.Ct. at 1359. The Court then clarified the test to determine whether a statute gives rise to a federal right that is enforceable under § 1983:
We have traditionally looked at three factors when determining whether a particular statutory provision gives rise to a federal right. First, Congress must have intended that the provision in question benefit the plaintiff. [Wright v. City of Roanoke Redevelopment & Hous. Auth., 479 U.S. 418, 430, 107 S.Ct. 766, 93 L.Ed.2d 781 (1987)]. Second, the plaintiff must demonstrate that the right assertedly protected by the statute is not so “vague and amorphous” that its enforcement would strain judicial competence. [Id. at 431-32, 107 S.Ct. 766], Third, the statute must unambiguously impose a binding obligation on the States. In other words, the provision giving rise to the asserted right must be couched in mandatory rather than prec-atory terms. [Wilder v. Virginia Hosp. Ass’n, 496 U.S. 498, 510-11, 110 S.Ct. 2510, 110 L.Ed.2d 455 (1990) ].
Id. 117 S.Ct. at 1359 (parallel citations omitted). If the existence of a federal right is established by satisfying these three requirements, the Court explained, there is a presumption that the right is enforceable under § 1983; but that presumption may be rebutted if Congress intended to foreclose a remedy under § 1983. See id. 117 S.Ct. at 1360.
In Blessing, the Court further provided specific guidance on the first prong of this inquiry — determining whether Congress intended, in a particular statutory provision, to benefit the individual seeking enforcement of the alleged federal right. The Court distinguished between provisions that are intended to benefit partieu-[751]*751lar individuals and thereby create “an individual entitlement to services” and those that are “designed only to guide the State in structuring its system wide efforts.” Id. 117 S.Ct. at 1361. Although provisions of the latter type may ultimately benefit individuals, the Court explained, they do so only indirectly and do not give rise to enforceable individual rights. See id. Instead, such provisions simply create “a yardstick” for the state to measure the systemwide performance of the program the state is operating pursuant to the statute. Id. The Court also emphasized that, rather than taking a blanket approach to determining whether a statutory scheme creates rights, courts must require plaintiffs to identify with particularity the specific rights that they believe arise from specific statutory provisions. See id. 117 S.Ct. at 1360-61.
With these principles in mind, we must analyze the statutory scheme in the case before us to determine whether it gives rise to any enforceable individual rights. The plaintiffs rely on our decision in Marie O. v. Edgar, 131 F.3d 610 (7th Cir.1997), to support their contention that the highway funding statutory scheme gives rise to individual rights enforceable through § 1983. In Marie 0., we concluded that the plaintiffs, infants with disabilities, were the intended beneficiaries of Part H of the Individuals with Disabilities Education Act (“IDEA”), because its provisions confer upon specifically identified individuals certain entitlements to specific services. See id. at 619-20.7
After reviewing STURAA, ISTEA, and the implementing regulations, we conclude that the statutory scheme in this case is like the one described in Blessing, rather than the one we had before us in Marie 0. The statutes themselves provide only very generally that recipients of federal highway funds must expend at least 10% of such funds with small business concerns owned and controlled by socially and economically disadvantaged individuals. See STURAA, Pub.L. No. 100-17, § 106(c)(1), 101 Stat. 132; ISTEA, Pub.L. No. 102-240, § 1003(b)(1), 105 Stat. 1914, 1919. The implementing regulations set out in great detail the obligations that recipients of federal highway dollars must fulfill with respect to minority participation. The regulations require recipients to submit for approval by the DOT a minority business enterprise affirmative action program; the regulations also specify various required program components. See 49 C.F.R. §§ 23.43, 23.45. The regulations further specify, for example, the manner in which states must calculate minority participation, requirements for record keeping, the eligibility standards that states must apply to applicants for DBE status, and the procedures that states must use when certifying disadvantaged businesses or when entertaining a challenge to a certification. See id. §§ 23.47, 23.49, 23.51, 23.53. In short, the regulatory requirements focus on what the states must do, in structuring their programs, to maximize the opportunity of minority businesses to participate in contracts financed with federal funds; the regulations -do not confer specific entitlements upon any individuals. Indeed, the 10% minority participation goal is for all DBEs combined; it does not guarantee that any one disadvantaged group will receive any contracts, let alone that any individual in any group will receive a contract or any other individual benefit. Therefore, because the statutes and regulations do not guarantee any specific benefit or service to any identifiable individual, we hold that the plaintiffs are unable to satisfy the first prong of the enforceable rights inquiry set out in Blessing[752]*7528 We therefore affirm the district court’s grant of summary judgment for the defendants on this claim.
B. § 1983 Claim Under the Fourteenth Amendment
The plaintiffs challenge the district court’s holding that their Fourteenth Amendment claim must fail on the merits because they have not demonstrated discriminatory intent on the part of the defendants.9 In order to establish liability under § 1983 for a violation of equal protection, the plaintiffs “must show that the defendants acted with a nefarious discriminatory purpose, and discriminated against [them] based on [their] membership in a definable class.” Nabozny v. Podlesny, 92 F.3d 446, 453 (7th Cir.1996) (citation omitted). We have explained:
The gravamen of equal protection lies not in the fact of deprivation of a right but in the invidious classification of persons aggrieved by the state’s action. A plaintiff must demonstrate intentional or purposeful discrimination to show an equal protection violation. Discriminatory purpose, however, implies more than intent as volition or intent as .awareness of consequences. It implies that a decisionmaker singled out a particular group for disparate treatment and selected his course of action at least in part for the purpose of causing its adverse effects on the identifiable group.
Id. at 453-54 (quoting Shango v. Jurich, 681 F.2d 1091, 1104 (7th Cir.1982) (cita[753]*753tions and internal quotation marks omitted)). “A showing that the defendants were negligent will not suffice. [The plaintiffs] must show that the defendants acted either intentionally or with deliberate indifference.” Id.
The plaintiffs point to only one piece of evidence admitted by the district court to show the defendants’ intent to discriminate against the plaintiffs on the basis of race: former Commissioner of IN-DOT Christine Letts’ comment to Harry Alford that she planned to satisfy the DBE requirements by giving business to the Harmon companies. Letts’ alleged intention to award contracts to the Harmon companies, which the plaintiffs repeatedly remind us are owned by a wealthy black businessman, hardly evinces any race-based discriminatory intent necessary to establish a violation of the Fourteenth Amendment under this count.
The plaintiffs also contend that the requisite discriminatory intent can be established by reliance on various items of evidence excluded by the district court: (1) Exhibits 22 and 23, which the plaintiffs maintain demonstrate that the Harmon companies and another company called CTeeh received a large share of the contracts awarded to DBEs; (2) the Indianapolis Disparity Study; and (3) the Gibson Reports. Even if these items were admissible,10 we cannot say that they show any race-based discriminatory intent on the part of the defendants.
The data contained in Exhibits 22 and 23 in no way demonstrates that the two companies were improperly certified or that the defendants were motivated by race-based discriminatory intent in certifying them or awarding contracts to them.
The Indianapolis Disparity Study also provides no evidence of discriminatory intent by the defendants in their administration of the statewide DBE program operated pursuant to the federal highway funding statutes. Instead, as its title suggests, the Indianapolis Disparity Study analyzes how the City of Indianapolis distributes its own construction money. The Study documents statistical disparities in the share of city-funded construction work that has gone to businesses owned by individuals of various minority groups compared to the percentages of businesses owned by members of those groups that are available to do the work. The Study also relates anecdotal evidence of discriminatory treatment of minority-owned businesses in the bidding process and by financial institutions. These findings, however, say nothing of the actions or motivations of the defendants named in this case in their administration of Indiana’s statewide DBE program for minority participation in federally funded highway construction projects.
Finally, we agree with the district court’s conclusion that the Gibson Reports are not probative of discriminatory intent in Indiana’s administration of its DBE program for federally funded highway construction. The Gibson Reports document weaknesses in Indiana’s program for minority participation in state-funded construction. They do not, however, provide any evidence of intentional race-based discrimination by the defendants in their disbursement of federal funds for highway construction.
We therefore must affirm the district ' court’s grant of summary judgment for the defendants on this claim on the ground that, the plaintiffs have failed to present evidence sufficient to support a finding of discriminatory intent.11
[754]*754C. § 1985 Conspiracy Claim
To establish a claim under 42 U.S.C. § 1985(3), a plaintiff must demonstrate four elements:
(1) a conspiracy;
(2) a purpose of depriving, either directly or indirectly, any person or class of persons of the equal protection of the laws, or of equal privileges and immunities under the laws;
(3) an act in furtherance of the conspiracy; and
(4) an injury to his person or property or a deprivation of any right or privilege of a citizen of the United States.
Trautvetter v. Quick, 916 F.2d 1140, 1153 (7th Cir.1990) (quoting Triad Assocs., Inc. v. Chicago Hous. Auth., 892 F.2d 583, 591 (7th Cir.1989)) (internal quotation marks omitted).
We agree with the district court’s conclusion that the plaintiffs have not presented a sufficient factual basis to permit a trier of fact to conclude that an express or implied agreement existed among the defendants (or between the defendants and other private contractors) to deprive the defendants of equal protection. As a threshold matter, we note that the absence of any underlying violation of the plaintiffs’ rights precludes the possibility of their succeeding on this conspiracy count. See Scherer v. Balkema, 840 F.2d 437, 442 (7th Cir.), cert. denied, 486 U.S. 1043, 108 S.Ct. 2035, 100 L.Ed.2d 620 (1988).
Moreover, we cannot accept the plaintiffs’ submission that they have presented sufficient circumstantial evidence to support an inference of a conspiracy to certify front DBE companies. The plaintiffs point to two portions of Harry Alford’s deposition. In the first part, Alford testified that Christine Letts told him that she planned to meet the required DBE goals by utilizing the Harmon companies. In the second portion, Alford testified that Letts pushed through the certification of the Harmon companies even though, in Alford’s opinion, they were ineligible for certification. Alford testified that the Harmon companies should not have been certified because their controlling owner is William Mays, a black businessman who, in Alford’s opinion, is too wealthy to qualify as a disadvantaged business owner. The plaintiffs further submit that other wealthy minority- or female-owned companies have wrongfully been certified and that the very fact that these front companies were certified supports an inference that a conspiracy existed between the defendants and the front companies.
Our review of this proffered evidence confirms the district court’s conclusion that the plaintiffs have not produced enough evidence for a reasonable trier of fact to infer the existence of a conspiracy. We cannot discern in Harry Alford’s testimony anything that indicates an agreement between any of the defendants or between any defendant and any contracting company. Nothing in Alford’s testimony indicates that Letts agreed with anyone else to certify the Harmon companies, let alone who that someone else might be. We note, moreover, that nothing in Alford’s testimony indicates that Letts thought the Harmon companies were ineligible for certification or that her alleged desire to certify them was motivated by the purpose of discriminating against the plaintiffs on the basis of race.
We also cannot accept the plaintiffs’ submission that the fact that certain alleged front companies were certified is sufficient to support an inference of a conspiracy. The implementing regulations do not require states to investigate the economic situation of companies who apply for certification; instead, states may apply a presumption of disadvantage to any company that is owned and operated by a member of one of the five categories of minorities. See 49 C.F.R. § 23.69 & App. A to Subpt. D.12 The burden is on third parties to [755]*755challenge certifications of companies that they believe are unworthy of certification. See id. Only when such a challenge is brought does a state have to investigate the economic situation of the company seeking certification to determine whether the presumption of disadvantage is rebutted. Notably, there is no evidence in the record that anyone challenged the alleged front companies, even though the regulations provide for such challenges. Therefore, even if Indiana has certified certain minority-owned businesses that in truth are too wealthy to qualify for certification, we cannot accept the argument that the fact of their certification alone evidences a conspiracy among the defendants to deprive the plaintiffs of their civil rights.
Moreover, even if the plaintiffs had established adequately a conspiracy to certify front DBE companies, they cannot establish that such a conspiracy, as described by the plaintiffs, constitutes a conspiracy to deprive the plaintiffs of equal protection on the basis of race. The plaintiffs’ primary complaint about the certification of the front companies is that those companies are too wealthy to justify certification. Among the allegedly wrongfully certified companies are the Harmon companies, which the plaintiffs themselves contend are owned by a black businessman, William Mays. Any conspiracy to certify rich DBEs therefore cannot be characterized as a conspiracy to deny the plaintiffs equal protection through race-based discrimination. As the plaintiffs themselves submit, one of the major beneficiaries of the defendants’ alleged wrongdoing is himself black.
In sum, we affirm the district court’s grant of summary judgment on the § 1985 claim. The plaintiffs have not adequately established a conspiracy; nor have they shown that the defendants’ purpose was to deprive the plaintiffs of equal protection.
Conclusion
In the opening paragraph of its order granting summary judgment, the district court opined that this case demonstrates the difference between rhetoric and proof in a court of law. Our own examination of the record and consideration of the parties’ submissions convince us that the district court’s characterization is an accurate one. Accordingly, the judgment of the district court is affirmed.
