Relocation of eastbound I-70 off-ramp to Holly Street and permanent closure of eastbound I-70 off-ramp to Dahlia Street

DENVER — As part of the Colorado Department of Transportation’s Central 70 Project, the eastbound Interstate 70 off-ramp to Holly Street will be permanently relocated to the east, closer to Forest Street, starting 5 a.m. on Nov. 5. This ramp relocation is required to accommodate the widened highway in this area. 

In addition to this ramp relocation, the I-70 off-ramp, currently located closer to Dahlia Street, will close permanently. Access to Stapleton South Drive from Colorado Boulevard will be maintained (see detour map below). 

TRAFFIC IMPACTS:

• Relocation of the eastbound I-70 off-ramp to Holly Street and permanent closure of the existing I-70 off-ramp to Dahlia Street — begins 5 a.m., Thursday, Nov. 5.

• Motorists will still be able to access Stapleton South Drive from Colorado Boulevard 

• This work is weather dependent and subject to change.

COVID-19 

Safe transportation infrastructure is essential for all of us, particularly for emergency first responders and freight drivers as Colorado navigates the COVID-19 pandemic. With that in mind, CDOT maintenance and construction crews follow social distancing and other health safety measures to reduce COVID-19 exposure on the worksite. The Colorado Department of Public Health and Environment announced guidelines for construction activities. The public is urged to join the campaign for #DoingMyPartCO by practicing social distancing and wearing face masks. As traffic returns to normal levels, motorists must drive cautiously and heed the speed limit so all of us can return home safely. 

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.
