Eastvale, CA - The County of Riverside Transportation Department has awarded Atkinson a $39 million contract for the I-5/Limonite Ave Interchange project in Eastvale, CA. Atkinson will improve the interchange and build a bridge over I-15—one of the most traveled freeways in Southern California. The project team will reconstruct the existing tight diamond interchange to a partial cloverleaf interchange with spread diamond ramps, loop entrance ramps, and a new bridge crossing over I-15 at Limonite Ave. The scope of work includes a 380-ft. x 150-ft. cast-in-place box girder bridge, as well as 200,000 cubic yards of excavation, 85,000 cubic yards of new roadway paving, pavement markings, and electrical installations. Atkinson will use a phased demolition and construction approach to keep the Limonite Ave bridge open to traffic during construction. Project completion is scheduled for February 2020.
