​Project location

US 51 (North of County V to WIS 22), Deforest to Leeds - Dane and Columbia counties

Project overview

This project will resurface 3.7 miles of US 51 from just north of County V near Deforest​ to the intersection with WIS 22/60 near Leeds in Dane and Columbia counties. The project will consist of removing the top 3 inches of asphaltic pavement and adding 4 inches of new hot mix asphalt. Additional work includes replacing guardrail end terminals and replacing two culvert pipes.​

The existing asphalt pavement is deteriorating, and treatment is needed to extend the service life of the roadway. Pavement distress data indicates that a preservation improvement concept will deter future pavement deterioration if completed before 2027.



  • 2028 - Construction anticipated, but advanceable to 2025 if funding is available

Traffic impacts/detours

US 51 will remain open to traffic with flagging operations. There is a potential for some night work to occur to minimize traffic impacts.
