Long term right lane closures begin on I-25 at Exit 11 as CDOT starts next phase of major infrastructure improvement project

August 18, 2021 - Southeastern Colorado - Temporary onsite detours will also be in place at the southbound I-25 on and off ramps at Exit 11

LAS ANIMAS COUNTY – Starting the week of August 22, the Colorado Department of Transportation will implement a right lane closure in both directions of Interstate 25 at the approaches to Exit 11. Other traffic impacts include temporary onsite detours at the southbound I-25 on and off ramps at Exit 11 and single lane closures on County Road 69.1. The closures and traffic shifts are necessary while crews begin rebuilding the off ramp and making infrastructure upgrades as part of the I-25 Exit 11 Interchange Improvement project just south of Trinidad. 

The project began on July 20 and is designed to upgrade facilities, add safety features, and improve access to Fishers Peak and area destinations. Work includes replacing a bridge, building ramp crossovers, constructing new roundabouts at the east and west sides of the interchange to improve traffic flow, adding pedestrian facilities, and making other infrastructure, safety, and aesthetic improvements to the area.
