Southeast gateway line

Introducing the Southeast Gateway Line Project (Formerly the West Santa Ana Branch)

The Southeast Gateway Line Corridor (SGL) project is more than just another rail line – it's a transformative 14.5-mile light rail transit (LRT) connection set to revolutionize the travel experience in southeast LA County. Boasting nine state-of-the-art stations, the new rail will link cities from Artesia to Downtown Los Angeles, passing through Cerritos, Bellflower, Paramount, Downey, South Gate, Cudahy, Bell, Huntington Park, Vernon, and the unincorporated Florence-Firestone area.

Construction work officially began on August 4 in the City of Artesia as Southern California Gas Company will be relocating existing gas lines to accommodate the future light rail project.
