Iowa Governor signed SF2478 into law on April 2, 2026, enacting transportation and infrastructure-related appropriations to the Iowa Department of Transportation. The bill provides for allocation and use of moneys from the Road Use Tax Fund and Primary Road Fund. It passed the Senate Appropriations Committee unanimously (Yea: 20, Nay: 0) during the 91st General Assembly. The legislation was formerly known as SSB 3186.

State agencies and transportation departments should begin implementing the funding allocations for fiscal year operations. Contractors and construction firms should monitor for new bidding opportunities on transportation infrastructure projects. Local governments relying on state transportation funding should coordinate with IDOT to ensure access to allocated funds. The bill is effective upon signing.
