The Urban-State Traffic Engineering Program (U-STEP) aims to solve traffic operation and safety problems on primary roads in Iowa cities. Eligible applicants include any Iowa city. Projects must involve a municipal extension of a primary road, with two types of projects eligible: spot improvements (limited to single locations) and linear improvements (spanning two or more intersections). The program provides 55 percent state funding, with a 45 percent city match for construction costs. An engineering analysis of the problem area is required, and the Iowa Traffic Engineering Assistance Program can be used for this analysis.
