Overnight full off-ramp closures on US 6: I-25 to Perry Street project

June 21, 2019 - Denver Metro Area, Colorado

 DENVER COUNTY — Overnight work is expected to occur between 10 p.m. and 5 a.m. from Sunday night, June 23 to Wednesday morning, June 26 on the north and southbound off-ramps from I-25 to westbound US Highway (US) 6 in Denver.

Work will include installing overhead signage, removing pavement marking, and restriping pavement on the off-ramps at mile point (MP) 284.4. The overnight closures are required to ensure the safety of motorists and crews during the project. The goal of this work is to reduce traffic congestion in this heavily traveled area.


Full closure of the off-ramps from I-25 to westbound US 6 during overnight work. Detours are as follows:

  • Southbound I-25 motorists should use Alameda Avenue as an alternate exit and connect back with US 6 via Federal Boulevard.
  • Northbound I-25 motorists should still use US 6 as an exit but will be directed to eastbound US 6 where they can turn around at Santa Fe Drive to 7thAvenue to Kalamath Street and get onto westbound US 6.
  • A single lane closure on westbound US 6 from I-25 to Perry Street will also be in place.
  • Ramp closures will be lifted after working hours.
  • Speeds will be reduced to 45 MPH during guardrail replacement operations.
  • There will be a 12-foot width restriction on vehicles 24/7 through the project zone.

To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project takes a systematic statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.
