US 6 & Wadsworth Boulevard Interchange Improvements

About the Project

Originally built in the 1950s, the US 6 and Wadsworth Boulevard interchange in Lakewood is receiving improvements to accommodate for the Denver Metro Area's population growth and increased traffic needs. CDOT has advanced improvements in phases as funding became available. The final, large undertaking to reconstruct the interchange and US 6 bridge, complete pedestrian and bicycle connections, and add additional noise walls is now underway.

Construction began with utility relocation and pre-construction activities in October 2026. This work is occurring on the frontage roads and side streets through October. The project is expected to be complete in late 2029.
