Located within the City of Grand Terrace, this project improved traffic congestion and lengthened the existing bridge to enhance local circulation and access to and from I-215. The project widened Barton Road from west of Grand Terrace Road to east of Vivienda Avenue, added a roundabout west of the bridge at the southbound on- and off-ramps, transitioned Michigan Street into a cul-de-sac and connected Vivienda Avenue to Commerce Way, realigned La Crosse Avenue, and lengthened the bridge to accommodate future freeway improvements.
