I-25 Exit 11 Interchange Improvements

Work this Week

  • Right lane closures are in place 24/7 in both directions of I-25 at the approaches to and at Exit 11 in Las Animas County.
  • The closure area extends from Mile Point 10, one mile south of Exit 11, to MP 12, one mile north of Exit 11.
  • The I-25 on and off ramps at Exit 11 are under 24/7 onsite detour configuration.
  • These detours consist of routing traffic onto temporary onsite pavement that runs adjacent to the existing ramps onto frontage roads.
  • Signage and construction cones are in place to alert motorists to the traffic shifts.

Exit 11 Current Traffic Patterns

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.

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 (see map above).
  • 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 (see map).
  • 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).
  • All roadways will remain open through the duration of the project.
  • Access to businesses and the Port of Entry will be fully maintained.
  • Lane closures and other traffic notices are posted weekly on COTrip.org.
