A highway expansion and transit project for the southern I-25 corridor, dubbed T-REX (Transportation Expansion Project), was completed on November 17, 2006. The project installed wider and additional highway lanes, and improved highway access and drainage. The project also includes a light rail line that traverses from downtown to the south end of the metro area at Lincoln Avenue. The project spanned almost along the highway with an additional line traveling parallel to part of I-225, stopping just short of Parker Road.
