Airport Road

CO 119 Airport Road Traffic Shift Detour Map. Details in the caption.
The safety improvements at the intersection of CO 119 and Airport Road, highlighting the northbound one-way traffic shift on Airport Road indicated by green arrows. A red-shaded widened shoulder along the west side of the road and yellow-coded Bus Lane Only sections approaching the intersection from both the Boulder and Longmont directions. Three purple dashed areas mark the installation of new raised crosswalks at the main intersection to enhance pedestrian safety.

Improvements include:

  • Eliminating left turns from Airport Road onto CO 119
  • Converting Airport Road between northbound and southbound CO 119 to one way northbound
  • Eliminating left turns from southbound CO 119 onto southbound Airport Road
  • Adding raised crosswalks at the turn lanes on southbound Airport Road and southbound CO 119
  • New bus queue bypass lane on southbound C0 119

Design update following June 2022 community meeting: Access from Ogallala Road to northbound Airport Road will be maintained.

Phase 1 of Safety Improvements

An aerial map showing Phase 1 of Airport Road safety improvements. Red hatched areas show a right lane and turn lane closure on southbound Airport Road just north of CO 119, and a lane closure in the Airport Road median between northbound and southbound CO 119.
An aerial map showing Phase 1 of Airport Road safety improvements. Red hatched areas show a right lane and turn lane closure on southbound Airport Road just north of CO 119, and a lane closure in the Airport Road median between northbound and southbound CO 119. One northbound lane remains open in the Airport Road median. The middle lane in the median is protected by traffic barriers, indicated by orange dotted lines, to create a pedestrian and cyclist detour. A green line shows the pedestrian and cyclist detour.

Traffic Impacts

  • Right lane and right turn lane closure on Airport Road just north of CO 119/Diagonal Highway
  • Northbound Airport Road median reduced to one lane. The two northbound left lanes on Airport Road, between northbound and southbound CO 119/Diagonal Highway, will be closed
  • Partial closure of the trail at Airport Road between northbound and southbound CO 119/Diagonal Highway.

Detours and Alternate Routes

  • When the Airport Road median becomes a northbound one-way road, travelers can use 83rd Street to access northbound CO 119/Diagonal Highway
  • Travelers turning right from southbound Airport Road onto southbound CO 119/Diagonal Highway can turn from the southbound lane
  • Pedestrians and cyclists will use the crosswalks on the east side of the intersection, travel southbound in the Airport Road median and turn left to connect with the trail in the median
  • To provide this detour for pedestrians and cyclists, a lane will be closed in the Airport Road median, and a temporary trail surface will be added to connect to the trail between northbound and southbound CO 119/Diagonal Highway. Traffic barriers will protect the area in median from vehicles.
