About the Project
This project entails upgrading the infrastructure and making safety, traffic flow and aesthetic improvements at I-25/Exit 11 just south of the City of Trinidad. Specific work includes ramp and lane widening and building crossovers; bridge replacement; building roundabouts to improve traffic flow; building retaining walls; improving access to the Port of Entry; retrofitting curb ramps for ADA compliance; adding guardrail and other safety features to the new bridge for pedestrians and cyclists, and incorporating urban streetscapes and new lighting and signage.

Work Schedule
- Work began on July 20, 2021 with an estimated completion date of November 2022.
- Current working hours are 7 a.m. to 6:30 p.m.
- No weekend work is expected.
Traffic Impacts
- 24/7 right lane closures are in place in both directions of I-25 from Mile Point 10 to MP 12 which is one mile south and north of and at Exit 11.
- A 17-foot width restriction exists within the project limits on I-25 and at the on and off ramps at Exit 11 until further notice.
- The southbound I-25 off ramp at Exit 11 is under a temporary detour configuration with traffic routed onto Toupal Drive, which is adjacent to the existing off ramp.
- Access to the on ramp to southbound I-25 at Exit 11 is also under a temporary onsite detour configuration via County Road 69.1.
- The northbound I-25 on and off ramps are also under temporary onsite detour configuration onto the frontage roads. Traffic is being shifted to accommodate ramp, roundabout and other construction.
- Guests exiting the Rodeway Inn are being routed onto CR 69.5 (unmarked road just south of the hotel entrance) behind the hotel, then back to the Santa Fe Trail to a new four way stop intersection. From there, signage will show the routes to north/south ramps.
- Motorists should exercise caution entering and exiting ramps and follow the signs.
- 12-foot lanes continue to exist in both directions of County Road 69.1, Toupal Drive and CR 69.3 (Santa Fe Trail).
- Access to businesses and the Port of Entry will be fully maintained.
- Lane closures and other traffic notices are posted weekly on COTrip.org.
