Drew Dix Parkway Dillon Drive at I-25 Interchange

About the Project:

This safety and mobility improvement project will construct a roundabout at the intersection of Drew Dix Parkway and the west frontage road. The southbound I-25 off-ramp at Drew Dix Parkway (exit 104) will be realigned to utilize the new roundabout.

The east frontage road will be built between Drew Dix Drive and Dillon Parkway. This new connection will run parallel to northbound I-25 between the existing roundabout at Dillon Drive and the Drew Dix Parkway / northbound I-25 on-ramp intersection.
