How two rival agencies merged to build Los Angeles' massive transit network
In short: Los Angeles County is the most populated county in the United States, and its mobility is driven by a massive, complex transit agency. Born from the merger of two competing organizations, the Metro system now manages everything from light rail and buses to regional commuter rail and freeway improvements.
The Los Angeles County Metropolitan Transportation Authority, known as Metro, is a state agency rather than a part of the county government. Following the merger of the Los Angeles County Transportation Commission (LACTC) and the Southern California Rapid Transit District (RTD), the entity was officially created on February 1, 1993. Before this merger, the agencies were often in conflict. During the 1980s, disputes between them even threatened service connectivity; for instance, the LACTC planned to end the Blue Line at Pico Station, despite the RTD building the 7th Street/Metro Center station just six blocks north.
Currently, Metro functions as a vast network, ranking as America's second-largest public transit system in terms of passenger numbers. As of the second quarter of 2026, the system saw a weekday ridership of 970,600, following a total ridership of 305,706,300 in 2025. The agency's reach is vast, operating across a 1,433 square mile area and employing 10,290 people. Its rail network includes 125.1 miles of urban rail service across 110 stations, including lines like the A Line, B Line, C Line, D Line, E Line, and K Line.
Beyond rail, Metro manages a complex web of bus services, including local routes, Metro Rapid, and the Metro Busway. It also provides funding for regional services like Metrolink and various municipal bus operators. To manage the diverse needs of its 10.1 million residents, the agency oversees everything from bike paths and pedestrian facilities to freeway service patrols and high-occupancy toll lanes.
