On X29 over rabbit creek in clayton county - bridge replacement - continuous concrete slab bridge (CCS)

The Federal Highway Administration (FHWA) awarded the Iowa Department of Transportation a formula grant of $348,402 under the Bridge Formula Program (CFDA 20.263) on November 10, 2025, for the replacement of the X29 bridge over Rabbit Creek in Clayton County, Iowa. The project will deliver a continuous concrete slab (CCS) bridge structure, with an anticipated completion date of September 30, 2029. This award funds highway bridge replacement infrastructure designed to address bridge conditions and improve public road safety in accordance with the Infrastructure Investment and Jobs Act (P.L. 117-58).

The Bridge Formula Program apportions federal funding to states based on a formula tied to the relative costs of replacing bridges in poor condition and rehabilitating bridges in fair condition. As the state transportation authority, the Iowa Department of Transportation's Operations and Finance Division serves as the prime recipient and fiscal administrator for this grant, managing execution of the bridge replacement project through completion within the four-year performance period.
