The Colorado Department of Transportation and their contractor, beginning Monday, July 27, are rehabilitating the Gallinas Bridge on Interstate 25 near Exit 6 between Trinidad and Raton N.M.
The cost of the project is $611,000 and is expected to continue until Oct. 15.
According to CDOT, work includes upgrading the deck, repairing joints, wrapping the girders with fiber-reinforced polymer for “shear and flexure strengthening” and “making other safety improvements to extend the bridge’s lifespan.”
The bridge spans the railroad tracks and Raton Creek at Exit 6 on Interstate I-25 over Raton Pass. It also marks the access point to the Santa Fe Trail Ranch subdivision.
CDOT listed the travel impacts as follows:
— Single lane closures in place under flagger control during construction activities.
— Short delays while flaggers allow alternating north/southbound traffic to pass at the approach and after the bridge.
— Motorists will need to slow down as they approach the bridgework zones, drive with caution and give themselves extra travel time.
Working hours are 7 a.m. to 5 p.m. with no night, weekend or observed holiday work expected.
“This is a two-step Federal Aid project to rehabilitate the Gallinas Bridge to meet current Federal Highway Administration load and safety standards,” wrote CDOT. “The first step in the rehabilitation process involves pressure-injecting epoxy into cracks to shore up the surface structure. The second step consists of wrapping the longitudinal girders with Fiber Reinforced Polymer (FRP) for shear and flexure strengthening.”
CDOT reminded the public that all construction schedules are weather dependent and subject to change and that lane closures and other traffic notices are posted weekly on COTrip.org. The public can also email email@example.com, or call a 24-hour hotline at 719-565-7570.
