Conejos County — The Colorado Department of Transportation and contract partner WW Clyde have completed bridge improvements at two locations over the Conejos River on US Highway 285. The project cost approximately $2.8 million and took advantage of low water flows over the winter season to successfully complete improvements on May 1.

“Bridges are critical infrastructure along our highway system requiring frequent monitoring, inspections and upkeep, ” said CDOT Regional Transportation Director Julie Constan. “These improvements add years of life to the structures ensuring goods and services are getting to our rural communities.”

The project removed an existing steel girder bridge and replaced it with a new concrete box structure at the northern location (Mile Point 7.82) improving water flow by providing a larger, more efficient, and structurally sound river crossing. The southern bridge (MP 7.59) received concrete deck repairs and a new asphalt overlay prolonging the life of the structure and providing a smoother road surface for motorists.

A new project will be underway this summer to improve three additional bridges in south-central Colorado. To learn more visit the project webpage: codot.gov/projects/sccobridges
