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 winter 2018. 

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 northbound and southbound I-25 as well as periodic ramp closures. Traffic will be maintained during peak travel times throughout construction.

CDOT, Hamon Infrastructure, the City of Westminster, the City and County of Broomfield, the City of Northglenn, the City of Thornton and Adams County would like to thank motorists for their patience during construction and remind drivers to slow down in the cone zone.
