Traffic signal work resumes in Aspen

Staff report

Aspen, CO, Colorado

ASPEN – The Colorado Department of Transportation will restart a project it initiated last fall to upgrade Highway 82 traffic signals on the outskirts of Aspen and on Main Street in the downtown area.

Work is set to begin April 16 and continue through the end of May.

A public open house will be held April 2 from 4:30 to 6 p.m. in the Aspen City Council chambers at City Hall. Information about the project and potential impacts to vehicle and pedestrian travel will be available, and representatives from CDOT and the project contractor will be on hand to answer questions.

The project involves work at all of the signalized intersections between the Aspen-Pitkin County Airport and Galena Street, with the exception of the Cemetery Lane intersection. The work includes installing traffic-signal loops, pedestrian push-buttons, underground conduits, fiber-optic cable and communications systems that will link the signals together for improved traffic management. When completed, the traffic lights will communicate with one another, providing the optimal signal cycle times for traffic in the corridor, according to CDOT.

The Cemetery Lane traffic signal will not be interconnected with the other signals because it lies between the roundabout and the S-curves in Aspen, which create too many variables in traffic flow. There are currently cameras at Cemetery Lane, and CDOT could install detection loops at the intersection in the future.

Almost all of the work has been completed already at the intersections outside of town, according to Bill Crawford, CDOT project engineer. Work alongside Highway 82 will be conducted this spring, though, requiring closure of shoulders around the intersections from the airport to Truscott Place.

Conversely, almost none of the work has been accomplished at the signalized intersections in downtown Aspen.

“The goal is to have traffic be affected at only one intersection at a time,” Crawford said in a statement. “The work will begin at the Aspen Street intersection and then move progressively from signal to signal.”

Each intersection will be under construction for about a week as the contractor places the traffic-signal loops and bores the conduits for the signals. No asphalt cuts should be necessary because the conduits will be placed with a boring machine, according to CDOT.

Some lane closures in downtown Aspen will be required to accomplish the work. They will be timed to avoid peak commuting periods in and out of town on weekdays.

Parking will be closed on Main Street and the half-blocks of side streets when intersections are under construction. The city will give a 72-hour notice of parking restrictions before work commences.

W.L. Contractors, of Arvada, has the $675,000 contract for the project.
