I-70 and Kipling North Phase Interchange Improvements

 Project Complete!

CDOT will begin construction on the north side of the I-70/Kipling Street interchange in mid-July. Changes will include removal of the congested 49th Avenue traffic signal and construction of a second right turn lane from the westbound I-70 off-ramp onto Kipling Street. This project will relieve congestion on the westbound I-70 off-ramp and improve traffic flow northbound on Kipling through the W. 50th Avenue intersection.

These “North Phase” changes are first steps building towards the ultimate interchange configuration. In early 2019, CDOT completed the environmental clearance for reconstruction of the I-70/Kipling Street interchange (click the Project Planning/Environmental Phase button for full details). Due to funding limitations, CDOT plans to phase implementation of the interchange reconstruction. Timing of the remaining improvements is dependent upon availability of additional funds.

 The “North Phase” project will:

  • Widen the westbound I-70 off-ramp for a second right turn lane onto Kipling and reconstruct the traffic signal
  • Remove the existing 49th Avenue traffic signal and convert that intersection to right-in/right-out turn movements
  • Widen the westbound approach at the Kipling/50th Avenue traffic signal to add a second left turn lane
  • Modify striping for traffic movements along the North Frontage Road
  • Replace aging traffic signal equipment at the eastbound I-70 off ramp intersection
