Southeast Gateway Line

(Formerly West Santa Ana Branch Transit Corridor)

The Los Angeles County Transportation Authority (LACMTA) proposes to implement a light rail transit (LRT) system along a corridor of about 19 miles that would connect several cities and communities along its alignment from its northern terminus in downtown Los Angeles (Union Station) and its southern terminus at the Pioneer Station in the City of Artesia in Los Angeles County, California. The Project’s initial segment, and Locally Preferred Alternative (LPA) consists of a 14.8-mile light rail transit segment that would connect several cities located between its termini at the Slauson/A Line (Blue) connection and Pioneer stations in Los Angeles County, California. It includes nine stations, five with parking facilities, and a Maintenance and Storage Facility. The Project is part of the larger 19.3-mile LRT corridor that would connect to Los Angeles Union Station Metro station. The Project’s current estimated capital cost is between $4.9 billion and $5.1 billion.
