February 6, 2020 - Denver Metro Area, Colorado - Westbound I-70 traffic shift at Brighton Boulevard Requires overnight closures of I-70 lanes and off-ramp to Brighton

DENVER — As part of the Colorado Department of Transportation’s Central 70 Project, westbound Interstate 70 lanes at Brighton Boulevard will shift south into the old eastbound I-70 lanes. 

To prepare for this shift, the westbound I-70 off-ramp to Brighton Boulevard and two lanes of westbound I-70 will close starting at 10 p.m., Thursday, Feb.6, and will reopen at 5:30 a.m., Friday, Feb. 7. Once the traffic shift is in place, three lanes of traffic will be maintained in each direction on I-70. 

This new traffic alignment will be in place for an extended period of time. See graphic below -- yellow represents westbound I-70 lanes and blue represents eastbound I-70 lanes. 

This shift will allow crews to demolish portions of the I-70 bridge over Brighton Boulevard, which is currently scheduled for a weekend in mid-February (details to follow). 


  • Ramp from westbound I-70 to Brighton Boulevard full closure – Thursday, Feb. 6, 10 p.m. to Friday, Feb.7, 5:30 a.m. Motorists will use Washington Street as an alternate route. 

  • Double lane closure on westbound I-70 at Brighton Boulevard – Thursday, Feb. 6, 10 p.m. to Friday, Feb.7, 5:30 a.m. One lane of traffic will remain open on westbound I-70 at Brighton Boulevard. 

This work is weather dependent and subject to change. 


Whole System.Whole Safety 

Earlier this year, CDOT announced its Whole System — Whole Safety initiative to heighten safety awareness. This initiative 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.
