I-25 Exit 11 Interchange Improvements

Work this Week

Nov., 2021

  • 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).

  • 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.
