Alameda Corridor-East Project

The San Gabriel Valley Council of Governments (SGVCOG), a joint powers authority comprised of 30 cities and three Los Angeles County supervisorial districts, created the Alameda Corridor-East (ACE) Construction Authority in 1998 to provide direction and oversight of the ACE Project to mitigate the impacts of significant increases in freight rail traffic on over 70 miles of mainline railroad in the San Gabriel Valley. In 2017, the SGVCOG was restructured and the SGVCOG Capital Projects and Construction Committee was established as a successor to the ACE Construction Authority with full responsibility for implementing the ACE Project. The ACE Project consists of a comprehensive program of safety improvements and mobility upgrades at 39 railroad crossings and 19 roadway-railroad crossing grade separation projects at an estimated cost of $1.7 billion. The ACE Trade Corridor is among the state's and nation's busiest rail corridors, carrying 16 percent of all oceangoing containers throughout the entire United States. The grade separations will improve crossing safety, eliminate vehicle delay throughout the local network and locomotive horn noise, and reduce emissions.
