CO 90 Bedrock/Dolores River Bridge Replacement

Time Lapse

BEDROCK BRIDGE IS MOVED... very carefully to provide the opportunity to be dismantled piece by piece, in hopes of finding a new home.

SH 90 Bedrock Bridge 2014

CDOT is removing the old Dolores River Bridge located on Colorado Highway (CO) 90 about four miles east of Bedrock and 15 miles east of the Utah-Colorado state line.

Crews will dismantle the old truss bridge and replace it with a new pre-cast concrete structure. The new bridge will provide several improvements for the driving public including wider and higher clearance for oversized vehicles.

A SEMA crew started work in December 2016 with construction expected to continue through the summer 2017. 

Traffic Impacts

Motorists will continue to use the temporary bridge installed just north of the old existing bridge. The temporary bridge allows for a detour of single-lane, alternating traffic under signal control. No over-sized/over-weight loads are allowed on the temporary bridge.

Work will take place Monday through Friday from sunup to sundown.

Project Facts 

  • Contractor: SEMA Construction
  • Cost: $3.8 million
  • Public Information Line: 970-385-1423


In the fall 2014, a crack was discovered in a beam of the original steel through-truss bridge. The damage forced the closure of the old bridge. A temporary bridge was constructed to allow single-lane, alternating flow of traffic controlled by a light signal.  

The Dolores River Bridge, a steel Pennsylvania through-truss bridge, was built in 1952. In 2002, the bridge was listed on the National Register of Historic Places for its architectural significance. The Dolores River Bridge is one of 10 remaining intact steel through-truss bridges statewide. Because of its historical significance, there is potential to have the old bridge relocated for use as a pedestrian/bike path structure.
