Travel Advisory

August 2, 2022 - Southeastern Colorado - Traffic will be detoured north to Exit 13B in Trinidad to access southbound I-25

Las Animas County – The Colorado Department of Transportation will implement a full closure of the Exit 11 on-ramp to southbound Interstate 25 from Monday, August 8 to Friday, August 12. The closure will be in place 24/7. During this closure, traffic will be detoured northbound on I-25 to Exit 13B Main Street in Trinidad to access southbound I-25. The ramp closure is necessary while crews connect the newly constructed elements at the southwest side of the Exit 11 interchange to the new on-ramp and County Road 69.1. After the full closure, the new west roundabout will open to traffic.

This work is part of the I-25 Exit 11 Interchange Improvement project that is currently underway. Other work includes paving the new bridge sidewalk and adding pedestrian fencing and safety features, finishing construction of the east roundabout, painting the retaining walls, building the ramp crossovers, and paving and performing concrete flatwork at the new west roundabout.
