PROJECT BACKGROUND

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 early 2019. 

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

About Express Lanes: Express Lanes increase roadway capacity and help to manage congestion on the highways. The use of toll pricing during peak travel times reduces delays, manages congestion and maintains reliable travel times. Express Lanes currently are open between 120th Avenue and US 36 on North I-25 and, US 36 from Denver to Boulder and on the I-70 Mountain Express Lane.
