Interstate 215:
Barton Road Interchange, Grand Terrace
SANBAG, Caltrans and the City of Grand Terrace are working to replace the Interstate 215 interchange at Barton Road. A Project Study Report was approved in April 2007, and the preliminary engineering/environmental document phase began in June 2007.
The preliminary engineering/environmental document phase will include a number of technical studies, including mapping, surveying, current and future traffic conditions, the impact to residents and property owners, the impact to sensitive plants and wildlife, public utilities, required right of way, and more. Once the studies are complete, the environmental document will be circulated for public review and comment, and the project will be considered for approval by Caltrans.
The project proposes to realign the freeway on-ramps and off-ramps, as well as realign Barton Road and La Crosse Avenue. It also involves the widening of Barton Road over the freeway. The new Barton Road interchange will help aid traffic operations by improving the flow of vehicles on the new bridge and ramps.
The interchange will accommodate the future widening of Interstate 215 through this area. This project is being accelerated ahead of the Interstate 215 widening project to provide earlier traffic congestion relief at this interchange.
The preliminary engineering/environmental document phase is expected to be completed by early 2010. Final design and right-of-way certification are estimated to be completed by 2013. Construction may begin by 2013 and end by 2015. These dates are estimates only.
Funding has not been secured. Estimated costs are $62 million in 2006-2007 dollars. A portion of the project costs ($.6million) will be funded by Measure I, the half-cent sales tax for transportation improvements in San Bernardino County. The Riverside County Transportation Commission will fund $.2 million of the project. The $59.8 million balance will be financed through future federal, state and local sources.
