County-State Traffic Engineering Program (C-STEP)
The County-State Traffic Engineering Program (C-STEP) funds county-led engineering projects to improve traffic safety and operations on Iowa primary roads outside city limits.
Funder: Iowa Department of Transportation
Due Dates: Rolling (Letters of request accepted all year)
Funding Amounts: Up to $200,000 per project for spot improvements; linear improvement limits range from $45,000–$150,000 per mile depending on project type and jurisdiction.
Summary: Supports Iowa counties in improving traffic safety and operations on primary roads outside city limits through targeted engineering solutions.
Key Information: County match required (typically 45% for spot, 40–70% for linear improvements).
Description
The County-State Traffic Engineering Program (C-STEP) is administered by the Iowa Department of Transportation to help Iowa counties address traffic operation and safety issues on primary roads located outside incorporated cities. The program funds engineering-based spot and linear infrastructure improvements, fostering collaboration between counties and the state to enhance roadway safety and efficiency. Projects must be based on a thorough engineering analysis and are intended to resolve specific traffic safety or operational problems.
