Adams County Curb Ramp Removal & Replacement

Project Update: 
Interchange improvements have begun along 120th. Operations will move east to west working on approximately 22 interchange locations. Additional locations within the Phase III project scope include Pecos Street, 92nd Ave and Church Ranch Road along US 36. Where Colorado Highway 121, Colorado Highway 128 and US 36 converge, multiple sections also will see improvements including US 36 eastbound and westbound ramps, Old Wadsworth Blvd, Wadsworth Pkwy, Uptown Ave and West 116th Circle. Each location is expected to take approximately two weeks to remove and replace curb ramps.
