Drew Dix Parkway / Dillon Drive at I-25 Newsletter

The Colorado Department of Transportation is making safety and mobility improvements to the Drew Dix Parkway / Dillon Drive interchange at Interstate 25 (exit 104). Construction does not directly impact I-25. However, drivers exiting or entering I-25 at this location will travel through the work zone.

Crews are currently preparing to shift traffic into a temporary configuration near the southbound I-25 off-ramp / Drew Dix Parkway intersection overnight on Saturday, June 3. The new configuration will be in place by 5 a.m. on Sunday, June 4. The southbound I-25 off-ramp will shift west to combine with Drew Dix Parkway and the west frontage road at a new temporary intersection. The west frontage road and Drew Dix Parkway will have stop signs while the southbound I-25 off-ramp will be given the right-of-way at the intersection. Access to all businesses will be maintained. 

This traffic pattern is expected to remain in place for several months while the roundabout is constructed. This arrangement will eliminate several traffic pattern changes by providing a large work area for roundabout construction.

CDOT is improving the Drew Dix Parkway/Dillon Drive interchange at I-25 (exit 104). Project benefits include improving traffic operations and mobility between Drew Dix Parkway, Dillon Drive and I-25.

This project constructs a roundabout at the intersection of Drew Dix Parkway and the I-25 west frontage road. The southbound I-25 off-ramp at Drew Dix Parkway will be realigned to utilize the new roundabout. The roundabout design will improve safety by eliminating existing conflicts associated with two closely spaced intersections on the west side of I-25.

A frontage road will be built between Drew Dix Parkway and Dillon Drive on the east side of I-25. This one-way northbound connection will run parallel to I-25 between the existing roundabout at Dillon Drive over I-25 and the Drew Dix Parkway/northbound I-25 on-ramp intersection.

This $10-million project builds on improvements made in 2016 as part of the Dillon Drive Interchange Project. SEMA Construction is the prime contractor. Construction completion is anticipated in fall 2024.
