Project to Build Temporary Bridge on CO 90 at Bedrock Begins Monday

October 30, 2014 - Southwestern Colorado/CDOT Region 5 - MONTROSE COUNTY – The Colorado Department of Transportation (CDOT) has issued a notice to proceed for construction of a temporary detour and temporary bridge structure over the Dolores River on SH 90 at Bedrock.

Oldcastle of Telluride, contracted for $1.03 million, will begin work on Monday, Nov. 3. It is estimated the project will be completed by January, weather permitting.

The existing 1952 steel through-truss bridge was damaged and repairs were completed in September; it remains open to all vehicle traffic less than 36 tons gross weight. However, CDOT plans to close the existing bridge once the detour and temporary bridge are in place to avoid the possibility of overweight vehicles crossing the existing bridge, and the possibility of further damage occurring.

CDOT Region 5 (southwest Colorado) requested and received approval from the State Transportation Commission for construction funding for the detour and temporary bridge installation. Engineers used expedited emergency contracting procedures to get a contractor on board quickly.

The detour alignment and temporary structure will be on the north side of the existing bridge. Once completed, the temporary bridge will be under signal control, single-lane traffic, with no weight restrictions. Over-width loads may not be allowed.

“We have begun design for a replacement bridge,” CDOT Region 5 Program Engineer Ed Archuleta said. “We anticipate construction on the new bridge can begin in 2016; we will continue to provide updates on this progress.”
