Interstate 215:
Barton Road Interchange, Grand Terrace
he Interstate 215 (I-215) Barton Road Interchange project will improve traffic congestion and lengthen the existing bridge to enhance local circulation and access to and from Interstate 215. Located within the City of Grand Terrace, this project also includes improvements to city sidewalks, adding bike lanes on Barton Road and a roundabout west of the bridge at the southbound on- and off-ramps. Some local streets will be reconfigured and improved, including Vivienda Avenue, Michigan Street and Commerce Way. All freeway ramps will be realigned and signals will be upgraded.
Project Features
- Widen Barton Road from west of Grand Terrace Road to east of Vivienda Avenue
- Add a roundabout west of the bridge at the southbound on-and off-ramps
- Transition Michigan Street into a cul-de-sac and connect Vivienda Avenue to Commerce Way
- Realign La Crosse Avenue
- Lengthen the bridge to accommodate future freeway improvements
Engineering & Environmental Studies
The Project Approval/Environmental Document phase of work requires a number of technical studies to be completed. Engineering studies include traffic volumes, mapping, public utilities, geotechnical reports, materials reports, drainage and storm water reports, and right of way needs. The results of these studies are used to develop cost estimates and prepare for future phases of the project – final design, right of way acquisition and construction.
