Travel Advisory

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). 

Traffic Impacts:

  • 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.
