Southern California Rapid Transit District

The Southern California Rapid Transit District (almost always referred to as RTD or rarely as SCRTD), was the successor to the original Metropolitan Transit Authority after it virtually went bankrupt. It was created by an act of the California State Legislature in 1964, and took over all of the bus service operated by MTA on November 5, 1964. RTD was merged into the Los Angeles County Metropolitan Transportation Authority in 1993.

RTD was created on August 18, 1964, to serve the urbanized Southern California region, including Los Angeles County, San Bernardino County, Orange County, and Riverside County. RTD replaced the major predecessor public agency, the Los Angeles Metropolitan Transit Authority, and ten different private bus companies in the Southern California region. RTD was placed in charge of creating a heavy rail public transportation system for Southern California, and for planning for bus improvements. In 1974, the El Monte Busway was opened, a bus-only lane (later converted to a high-occupancy vehicle lane). In 1973, RTD shed parts of its operations outside of Los Angeles County, (they were taken over by other agencies including what was then the new Orange County Transit District (now Orange County Transportation Authority) although it continued to operate inter-county service to Riverside and San Bernardino until the formation of LACMTA, and LACMTA continues to operate a line (460 express) to Disneyland in Orange County and one route (161 local) that serves Thousand Oaks, California, in Ventura County.
