Design Engineering and Preliminary Environmental Consulting Services are required by the Imperial County Public Works Department (County). The County proposes to replace the existing Brandt Road Bridge over Alamo River. The project includes the demolition, removal and disposal of the existing bridge, abutments, piles, road surfacing and approaches with replacement with a new single span bridge to be reconstructed on the same alignment. The purpose of the proposed project is to replace the existing, 1950 wood bridge with a new single span bridge crossing that would satisfy current design and seismic standards. The existing bridge is an approximate 150 foot long, ten-span bridge with all pile bents in the river. The proposed single span bridge will ensure the river flow is not impeded. Brandt Road is within the northern portion of the Imperial Valley, southwest of the city of Calipatria, CA and east of the Salton Sea. It currently carries predominantly agricultural and nearby geothermal industry traffic. However, its location is critical to the future Lithium Valley development in this area. The Lithium Valley is a recent, reference to a portion of the Imperial County unincorporated lands located at the southeast side of the Salton Sea in California. The State recently created the Lithium Valley Commission, directed to review, investigate, and analyze opportunities and benefits for lithium recovery and use in the State, as this and other minerals are being developed from geothermal brine in the Salton Sea Geothermal Resource Area. As geothermal, mineral and lithium extraction, and related heavy industries are exploring and proposing large projects in the area, the transportation infrastructure in this Lithium Valley are noticeably either lacking, or at risk of inability to serve this increased development. These areas have been, and still are also a significant part of the existing agricultural economy of the region and already at risk of transportation disconnects due to an aging transportation infrastructure network. Brandt Road, can address north-south traffic along a twelve-mile route, starting at the south at Hwy 78/86, between the cities of Westmorland and Brawley, finishing north at Sinclair Road where many heavy geothermal industries currently operate and is where the future of Lithium Valley is expected to develop. The bridge location is approximately 2.5 miles southwest of the city of Calipatria. The primary objective of the proposed project is to provide a safe and reliable crossing for the public that meets all current design standards, will support current agricultural and local traffic, and heavy geothermal, lithium & other metal extraction industry development in this area.
