A change to Tennessee prevailing wage law now affects highway construction contracts funded with federal or state dollars—and most contractors don't realize it yet.
Most Tennessee construction and trades owners know that prevailing wage requirements apply to certain state-funded projects. What many don't realize: as of May 21, 2026, prevailing wage now extends to any highway construction project using federal or state highway funds—a significantly broader category that affects far more contractors than before.
This change comes from Senate Bill 2229, which amended Tennessee Code Annotated Section 12-4-403(a). The provision is straightforward but carries real cost implications for businesses bidding on or performing work on public highways.
Under the amended law, prevailing wage rates must now be paid to workers on construction projects for public highways that use any federal or state highway funding. This applies to contracts entered into, amended, or renewed on or after the effective date of May 21, 2026.
The key word here is "any." If a highway project receives even partial funding from federal or state highway sources, the prevailing wage requirement kicks in. This is broader than previous law, which focused more narrowly on direct state contracts.
If your business performs construction work on public highways—whether that's new construction, maintenance, repair, or improvement—and the project uses federal or state highway funds, you're affected. This includes general contractors, subcontractors, and trades working on road projects funded through the Tennessee Department of Transportation, federal highway programs, or similar sources.
Even if you've never worked on a prevailing wage project before, you may now encounter these requirements when bidding highway work you previously didn't think required it.
Prevailing wage rates are typically significantly higher than standard market wages. In Tennessee, these rates vary by county and trade. The requirement applies to all workers on the project, not just a portion of your crew.
This directly increases your labor cost on affected contracts. When bidding highway projects starting May 21, 2026, you'll need to:
• Verify whether the project uses federal or state highway funding
• Look up the applicable prevailing wage rates for your trade and the project's county
• Factor those rates into your bid
• Maintain wage records and documentation for compliance
If you currently bid highway projects without accounting for prevailing wage, this change requires a shift in how you estimate labor costs.
The law became effective upon signature on May 21, 2026. The requirement applies to any contract entered into, amended, or renewed on or after that date. If you have existing highway contracts, check whether they're subject to amendment or renewal—that could trigger the requirement.
The specific amendment is found in Section 2 of SB2229, which modified TCA §12-4-403(a).
For contractors working in highway construction, understanding this change now—before you bid your next project—will help you price accurately and avoid cost overruns. Your industry association or bonding agent can help clarify how this applies to your specific work.
