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 for 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 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 SH 7. Motorists can expect the roadway to be in its final alignment by winter 2018.

“I-25 plays a critical role in the quality of life and economic vitality in the growth of northern Colorado,” said Paul Jesaitis, CDOT Region 1 transportation director. “This stretch is one of the most congested portions of highway in the Denver metro area, seeing an average daily traffic volume of 174,000 vehicles per day.”.

Construction will take place Monday through Friday, 7:00 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.

“Ultimately, this project will positively impact motorists, providing benefits to local businesses, neighborhoods as well as through traffic,” said Jesaitis. “We’re excited to get started.”

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.

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 Ave. and US 36 on North I-25 and, US 36 from Denver to Boulder and on the I-70 Mountain Express Lane.
