Entrance to C’dale work begins Monday
Aspen, CO Colorado
CARBONDALE ” The Colorado Department of Transportation will begin major reconstruction of the Highway 133 entrance to Carbondale on Monday, Nov. 5.
The $4.64 million project includes widening of the Highway 133 bridge over the Roaring Fork River from two lanes to four, adding a second turn lane on westbound ” or downvalley ” Highway 82 at its intersection with Highway 133, replacing the traffic signal at the intersection, constructing a retaining wall at the bridge, and drainage improvements.
Work on this project will proceed in several phases. The first phase, beginning this fall, includes installing temporary excavation shoring and constructing the bridge pier foundations and abutments. This work is scheduled while the Roaring Fork River water level is seasonally low, and to avoid the spawning seasons of various trout species in the river, according to CDOT. The work begins Monday and will continue through December.
Work will then resume in March 2008. Work next year will include constructing the new bridge deck for the bridge widening, placing traffic on the new structure and then removing and reconstructing the existing bridge deck, and tying the new and old bridge structures together with a raised median. The drainage improvements will begin in the spring, while the Highway 82 signal and turn-lane work will be done in the fall of 2008, after the bridge construction is complete.
Traffic impacts are anticipated to be minimal for most of the project, according to CDOT. The current two-lane traffic configuration over the existing bridge will be maintained throughout the project, with minor lane shifts at the approaches to the bridge. Crews will not interfere with traffic during weekday, peak traffic periods on either Highway 82 or Highway 133, CDOT said.
CDOT has contracted with SEMA Construction, Inc. of Centennial, Colo. for the project.
