San Gabriel Trench Project

The Alameda Corridor - East Construction Authority (ACE) proposes to construct its 2.35 mile San Gabriel Trench Project (Project) from the San Pascal Wash bridge in City of Alhambra, east through City of San Gabriel, to Walnut Grove Avenue in City of Rosemead, County of Los Angeles. The Project will grade-separate the Ramona Street, Mission Road, Del Mar Avenue and San Gabriel Boulevard grade crossings of Union Pacific Railroad Company's (UPRR) Alhambra subdivision main line tracks in the City of San Gabriel. ACE also proposes to substantially modify the Walnut Grove Avenue at-grade crossing located in City of Rosemead, to provide the railroad track profile required for the eastern approach into the trench. Table 1 below lists the at-grade crossings within the Project area and proposed modifications for each.
