U.S. 42 Improvements (from the bridge over Harrods Creek to River Road) - 5-972

Purpose	This project aims to reduce traffic congestion, improve mobility, and enhance safety along U.S. 42 from the bridge over Harrods Creek to River Road. The need for the project is generally derived from the current traffic congestion on U.S. 42, combined with the projected future traffic volumes and high crash rates.
Project Scope	Implement safety and mobility enhancements on U.S. 42 from the eastern end of the bridge over Harrods Creek to just east of River Road. The design work is being conducted following the 2022 Planning Study completed by the City of Prospect and the early 2011 design work completed by KYTC. Currently, the project scope includes Preliminary Engineering and Environmental Analysis to address four build alternatives. Should a build alternative be advanced, the scope will then move to the final design phase.
Alternatives/Build Options	The five alternatives currently under consideration include: Alternative 1: Keep the existing road; eliminate the signals with 3 roundabouts at the intersections and add pedestrian facilities. Alternative 1 - Roundabouts.pdf Alternative 2: Widening to the south for a 5-lane section throughout; keep the three signals and add pedestrian and multi-use facilities. Alternative 2 - 5 Lane Widen South.pdf Alternative 3: Access Management alternative between Timber Ridge and Fox Harbor. Alternative 3 - Access Management.pdf Alternative 4: Symmetrical widening for a 5-lane section throughout, and add pedestrian facilities. Alternative 4 - 5 Lane Widen Symmetrical.pdf Alternative 5: No build/no changes. These files are large and may take some time to download
