San Gabriel Trench Grade Separation Project
JMD provided professional engineering services with the Alameda Corridor East (ACE) and the City of San Gabriel for the grade separation near the historic San Gabriel Mission and adjacent vital Mission District, the San Gabriel High School, and numerous residential properties adjacent to the existing rail right-of-way. The rail trench will substantially reduce operating noise through the elimination of crossing warning horn blasts and signal equipment, and because the trench walls effectively reflect noise upward rather than outward. This project included rail coordination, utility, traffic control, and management planning.
JMD was responsible for grade crossing design, as well as the traffic element (signing and striping, traffic signals, traffic control, traffic management plan, and haul routes) for the San Gabriel Trench Project.
