I-25 Closed Nights of Oct. 4-5 from 136th to 120th Avenues for Storm Sewer Work

THORNTON—From 10 p.m. to 5:30 a.m. Oct. 4 through Oct. 5 and Oct. 5 through 6, southbound Interstate 25 will be closed between 136th and 120th avenues. During these closures, crews will install new storm sewer infrastructure beneath the highway. This work is a part of the North I-25 Express Lanes: 120th Avenue to Northwest Parkway/E-470 project.

Detour routes are expected to have up to 25-minute delays.

Traffic Impacts

  • Southbound I-25 between 136th and 120th Avenues
    To detour around these closures, motorists traveling on southbound I-25 will take the 136th Avenue exit to southbound Huron Street and then turn left onto eastbound 120th Avenue to I-25 southbound.

  • Motorists should expect delays and follow detours as directed. Detour routes are expected to have a delay of approximately 25 minutes, depending on traffic. The late-night weekday hours are scheduled to minimize traffic delays as much as possible.

Project Info

The North I-25 Express Lanes project from 120th Avenue to Northwest Parkway/E-470 is a $97.5 million project that will improve safety, capacity and user choice to a rapidly developing region.

This project will continue the previous Express Lanes project, which was completed on I-25 between US 36 and 120th Avenue, and will extend the Express Lanes to Northwest Parkway/E-470. The project will add capacity on I-25 up to Northwest Parkway/E-470 and construct a new asphalt surface from 120th Avenue to Colorado Highway 7. Motorists can expect the roadway to be in its final alignment by winter 2018.

Construction will take place from 7 a.m. to 4:30 p.m., Monday through Friday, with periodic night and weekend work. Motorists can expect various lane closures on both northbound and southbound I-25 as well as periodic ramp closures. Traffic will be maintained during peak travel times throughout construction.
