The Alameda Corridor is a 20-mile (32 km) freight rail "expressway" owned by the Alameda Corridor Transportation Authority that connects the ports of Los Angeles and Long Beach with the transcontinental mainlines of the BNSF Railway and the Union Pacific Railroad that terminate near downtown Los Angeles, California. Running largely in a trench below Alameda Street, the corridor was considered one of the region's largest transportation projects when it was constructed in the 1990s and early 2000s.

The Port of Los Angeles is a seaport managed by the Los Angeles Harbor Department, a unit of the City of Los Angeles. It occupies 7,500 acres (3,000 ha) of land and water with 43 miles (69 km) of waterfront and adjoins the separate Port of Long Beach. Promoted as "America's Port", the port is located in San Pedro Bay in the San Pedro and Wilmington neighborhoods of Los Angeles, approximately 20 miles (32 km) south of downtown.
