Old Dolores River Bridge to be Removed and Replaced with New Structure on CO 90
A crew will start work Monday, December 5 with construction continuing through the summer of 2017. Work will take place Monday through Friday from sunup to sundown.
SEMA Construction of Denver has been awarded the contract to 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. The project cost, including design and construction, is estimated at $3.8 million.
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 oversized/overweight loads are allowed on the temporary bridge.
BACKGROUND: Two years ago, in the fall of 2014, a crack was discovered in a beam of the original steel through-truss bridge. The damage forced the closure of the old bridge.
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.
