CDOT crews plan to convert the shoulder to an additional lane by restriping less than a mile of I-225 southbound from Yosemite Street to Interstate 25.

Drivers coming from DTC Boulevard, Yosemite Street, or E. Quincy Avenue will not have access to I-25 southbound.

A concrete barrier will restrict them to I-25 northbound.

Construction is set to begin by late October. CDOT hopes to complete the project a month later.

Specific construction dates have not been released.
