Project Background
In September 2016, the Town of Basalt began building a pedestrian underpass beneath CO 82, at mile point 23.1. The project will improve safety for all transportation modes by allowing non-motorist traffic to pass under the highway.
The completed underpass will connect the Roaring Fork Transportation Authority parking lot with the Basalt Store front and Bus Rapid Transit stations at the intersection. Residents will also have easier, more convenient access to schools to the north and south of the project.
The new, fully illuminated underpass is designed to be 140 feet long, 16 feet wide and up to 9 feet tall. The construction of the underground path, combined with the installation of new traffic signals and an upgraded storm water drainage system, is anticipated to improve the flow of traffic and pedestrian safety along the highway.
