rdf:langString The T Third Street is a Muni Metro light rail line in San Francisco, California. It runs along the east side of San Francisco – primarily in the median of Third Street – from Sunnydale to the Market Street subway. It is interlined with the K Ingleside line, forming a single service running between Sunnydale and Balboa Park. The line serves 21 surface stations, all of which are accessible. Most of the surface portion of the line runs in dedicated median lanes, though two portions operate in mixed traffic. Construction of the line was proposed in the late 1980s as plans for the redevelopment of the Mission Bay area were established. Construction took place in the mid-2000s. Limited service began in January 2007, with full service that April. It was the first line added to the Muni Metro system since the N Judah in 1928. In January 2023, the line will begin using the new Central Subway, a crosstown route from 4th and King to Chinatown. The Central Subway's weekend shuttle service between 4th and Brannan and Chinatown used since November 2022 and going until the main T Third Street switches over to the Central Subway presently brands its rolling stock as part of the T Third Street. From this point onwards, the K Ingleside will no longer be interlined with the T Third Street.
