Temporary Traffic Pattern Detours

The following is from Colorado Department of Transportation

Bridge construction continues under Research Parkway as part of the Powers Boulevard/ CO 21 and Research Parkway Interchange project

On Friday, January 14 CDOT will re-open Research Parkway on the west side of Powers Boulevard (CO21). Once opened, through-access will still be restricted on Research Parkway, through the interchange. CDOT will continue bridge and ramp construction as part of the new Diverging Diamond Interchange (DDI). This traffic configuration will be in place until the full DDI has been implemented, to allow for a safer work zone.

Other construction operations continue as crews work on Powers Boulevard at the Cottonwood Creek Bridge, continue constructing the new bridge, perform earthwork operations and underground drainage installation.

TRAFFIC IMPACTS:

Beginning Friday, January 14:

  • Research Parkway will have no direct through access across Powers Boulevard.
  • Northbound and southbound Powers Boulevard (CO 21) will continue to have no impacts.
  • Access to Powers Boulevard from Research Parkway on the west side will be limited to southbound access only, northbound and through access will use the signalized U turn south of the interchange.
  • Access to Powers Boulevard from Research Parkway on the east side will be limited to northbound access only, southbound and through access will use the signalized U turn north of the interchange.
  • Speed reductions to 45 MPH on Powers Boulevard (CO 21) and to 35 MPH on Research Parkway will be in place. Motorists should expect delays.
