Project Info

The North I-25 Express Lanes project from 120thAvenue 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 120thAvenue, 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.
