December 5, 2017 - Denver Metro Colorado/CDOT Region 1


ADAMS COUNTY – As part of the North I-25 Express Lanes: 120th Avenue to Northwest Parkway/E-470 project, the Colorado Department of Transportation and contractor partner, Hamon Infrastructure, will conduct an overnight northbound I-25 off-ramp closure at 136thAvenue in order to install safety-critical barrier.

Motorists should plan to add an additional 10 minutes to their travel time to detour around the closure.


Wednesday, Dec. 6, 2017 – 8 p.m. to 5:30 a.m. – Full closure of the northbound I-25 off-ramp to 136th Avenue: To detour around this closure, motorists traveling on northbound I-25 will exit at 120th Avenue, proceed east to Washington Street, then turn north on Washington Street to reach 136th Avenue.



Motorists can also expect single right lane closures next week on northbound I-25 between 128th and 136th Avenue on Monday through Wednesday, from 8:30 a.m. to 2 p.m. and on southbound I-25 between 128th and 136th Avenue on Thursday and Friday from 11 a.m. to 3 p.m. Crews will also require a single right lane closure overnight on northbound I-25 between 144th Avenue and Northwest Parkway/E-470, Monday through Wednesday from 8 p.m. to 5:30 a.m.


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 Friday7 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.
