The Placer County Board of Supervisors paved the way Sept. 9 for construction to begin as early as this fall on a congested roadway, according to a press release from the county’s Public Information Office. Board members voted to approve plans and specifications and authorize the county Public Works Department to go out to bid on the construction of a partial cloverleaf interchange at Highway 65 and Sunset Boulevard. The project will eliminate the last at-grade intersection with traffic signals on Highway 65 between Interstate 80 and Lincoln. Construction is scheduled to begin late this fall if weather permits and to be completed in 18 to 24 months. The projected construction cost is $28.5 million. Placer County, Rocklin and Roseville are contributing funding through the Highway 65 Joint Powers Authority, an agency they created to help finance four interchanges along Highway 65. Funding for the JPA comes from traffic-mitigation fees paid by new developments. The interchanges at Stanford Ranch Road-Galleria Boulevard, Pleasant Grove Boulevard and Blue Oaks Boulevard have already been built. The United Auburn Indian Community is contributing approximately $4.7 million to the Sunset Boulevard project. The Sunset interchange will have a partial-cloverleaf design with a circular onramp to move westbound Sunset traffic to the highway’s southbound lanes and a circular onramp for eastbound motorists on Sunset who want to head north on the highway. The interchange will feature a six-lane overpass for Sunset and allow for Highway 65 to eventually be widened to eight lanes with auxiliary lanes.
