Third Street Grade Separation at BNSF Railroad

The project involves the construction of a grade separation underpass at Third Street and the BNSF Railroad tracks in Riverside, California, encompassing a comprehensive range of civil, structural, and utility improvements. Key elements include the build-out of a quadruple-track concrete bridge structure, extensive excavation and grading of Third Street over approximately 1,340 feet, and the installation of new paved roadway elements such as curbs, gutters, sidewalks, wheelchair ramps, driveways, and retaining walls. The scope further requires the reconfiguration of adjacent local streets, relocation and realignment of both wet and dry utilities, including the Riverside Canal, and the construction of storm drainage infrastructure consisting of pipes, catch basins, a new pump station, and a stormwater detention basin. Traffic signal modifications, new signage and striping, landscaping, and irrigation systems are also part of the work, alongside the demolition and removal of two acquired properties.
