The Los Angeles Metropolitan Transit Authority
(sometimes referred to as LAMTA
or MTA I
) was a public agency formed in 1951. Its original mandate was to do a feasibility study for a monorail
line which would have connected Long Beach
with the Panorama City
district in the San Fernando Valley
via Downtown Los Angeles
The agency's powers were expanded in 1954, authorizing it to study and propose an extensive regional transit system. In 1957, another expansion of the agency's powers authorized it to operate transit lines, and it subsequently purchased the bus and streetcar lines then being operated by Metropolitan Coach Lines, which had taken over passenger service of the Pacific Electric Railway
in 1951, as well as the bus and streetcar lines of the Los Angeles Transit Lines, successor to the Los Angeles Railway
. The MTA began operating the lines on March 3, 1958, and continued to do so until the agency was reorganized and relaunched as the Southern California Rapid Transit District
in September 1964.
During the MTA's tenure, the last remaining rail transit lines in Los Angeles were abandoned and replaced with bus service, the last former Pacific Electric line in 1961, and the last former Los Angeles Railway lines in 1963.
