Hours for pedestrian tunnel under I-25 near 120th Avenue extended for special event Sept. 15 and Sept. 16

September 15, 2017 - Denver Metro Colorado/CDOT Region 1 - NORTHGLENN – For the City of Northglenn Pirate Fest, the Colorado Department of Transportation will temporarily extend the hours of the pedestrian tunnel under I-25 near 120th Avenue from 6:30 a.m. to 11:30 p.m. on Friday, Sept. 15, and Saturday, Sept. 16 from 6:30 a.m. to 10:00 p.m.

 The pedestrian tunnel links to the RTD Wagon Road Park-n-Ride and is currently only open to the public Mondays through Fridays from 6:30 a.m. to 5:30 p.m. This tunnel is closed at all other times so CDOT crews can complete the extension of both the east and west side of the tunnel as part of the North I-25 Express Lanes: 120th to Northwest Parkway/E-470 project.

This event is weather-dependent and schedules are subject to change.


  •  Westbound - To access the trail from westbound Community Center Drive, travel north to Grant Street, west to 120th Avenue, and south to Delaware Street and rejoin the trail at the RTD Wagon Road Park-n-Ride.
  • Eastbound - To access the trail from the RTD Wagon Road Park-n-Ride, travel north to Delaware Street, east to 120th Avenue and south to Grant Street to rejoin northbound I-25.


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 pedestrians and bicyclists for their patience during construction.
