The T Third Street is a Muni Metro light rail line in San Francisco, California. It runs along the east side of San Francisco from Sunnydale to Chinatown, traveling in the median of Third Street for most of its length before entering the Central Subway as it approaches downtown. The line serves 22 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.
Limited service began in January 2007, with full service starting in April of the same year. The line was rerouted north of 4th and King to travel through the Central Subway to Chinatown on January 7, 2023. It was the first line added to the Muni Metro system since the N Judah in 1928.
Operations
[edit]Route
[edit]The T Third Street's northern terminus is Chinatown station inside the Central Subway. Trains operate south below Stockton Street to Union Square/Market Street station, which offers a connection to Powell Street station as the line does not enter the Market Street subway. The line then tunnels underneath 4th Street to serve Yerba Buena/Moscone station in the SoMA district before surfacing south of the Interstate 80 bypass, where it serves a stop at the 4th and Brannan station. The T then crosses the existing N tracks at 4th and King and continues south to 3rd Street. Additional short turn service between Chinatown and Mission Bay Loop will be later added.[3][4] The line runs south through the Mission Bay neighborhood in a dedicated median, passing the Mission Bay Loop between 18th and 19th Streets, which is used to allow trains to turn around at Mission Bay or to hold special trains to serve events at Chase Center.
The line continues south through Dogpatch and across Islais Creek into the Bayview and Hunters Point neighborhoods. It runs in mixed traffic for 1⁄2 mile (0.80 km) from Kirkwood Avenue to Shafter Avenue, then returns to dedicated lanes. A wye, occasionally used for short turning trains, is located at Armstrong Avenue. The line crosses the U.S. Route 101 freeway, where Third Street becomes Bayshore Boulevard, and continues south in the median. The southern terminus of the line is at Sunnydale station in the Visitacion Valley neighborhood.
Service
[edit]The T Third operates seven days a week, beginning at 5 a.m. weekdays, 6 a.m. Saturdays and 8 a.m. Sundays, operating until 1 a.m. Service is provided by the 91 Owl overnight bus during the hours that rail service is not running. On weekends, T Third Street Bus service runs from 5am until the start of rail service. The bus line largely follows the rail line, but it uses surface streets to parallel sections where the rail line has dedicated rights-of-way.
History
[edit]Background
[edit]Third Street (and its extensions south) had streetcar service operated by the Market Street Railway until 1941, when repaving allowed the transit operator to replace the line with buses.[5][6] The 15 Third Street bus was discontinued with the beginning of light rail service.[7]
Construction
[edit]![](http://upload.wikimedia.org/wikipedia/commons/thumb/9/9c/Third_Street_Light_Rail_construction_at_Marin_Street_station%2C_March_2005.jpg/220px-Third_Street_Light_Rail_construction_at_Marin_Street_station%2C_March_2005.jpg)
Construction of the line was proposed in the late 1980s as plans for the redevelopment of the Mission Bay neighborhood were established. Construction took place in the mid-2000s. The line was constructed as the Third Street Light Rail Project. Testing on the line took place in summer 2006,[8] with limited service starting on January 13, 2007, and full service beginning on April 7, 2007.[9] T Third Street service was initially operated between Castro station and Sunnydale station. Following service changes on June 30, 2007, the T Third Street and the K Ingleside lines were interlined through the Market Street subway and Twin Peaks tunnels, resulting in a combined route from Balboa Park, through downtown, to the Visitacion Valley neighborhood.[10]
The Mission Bay Loop project, which added a short turn loop using 18th, Illinois, and 19th, was constructed to supplement the Central Subway project. The loop was originally designed in 1998 as part of the Third Street Light Rail project, but was deferred due to insufficient funding. A $3.5 million construction contract was issued in 2014.[11] Construction started in July 2016 and was completed in 2019.[12] Another loop at 25th and Illinois is proposed to increase short-line service frequency between Downtown and Dogpatch.[13]
Later changes
[edit]The underground section of the line was closed west of Castro station from June 25 to August 24, 2018, due to the Twin Peaks Tunnel shutdown.[14] On August 25, 2018, at the conclusion of the shutdown, Muni began running permanently two-car trains on the K/T line (as had been used east of Castro during the shutdown).[15] The line was shut down again, from January 22, 2019, until April 1, 2019, for construction of a new platform at UCSF/Mission Bay station.[16][17] In April 2019, the SFMTA ended the use of unscheduled short turns. These had been used to provide more consistent service on the inner portion of the line, but had caused inconsistent and less frequent service in the Hunters Point-Bayview and Visitacion Valley neighborhoods.[18]
On March 30, 2020, Muni Metro service was replaced with buses due to the COVID-19 pandemic.[19] Rail service returned on August 22, with the routes reconfigured to improve reliability in the subway. T Third Street and M Ocean View light rail lines were interlined, running between Sunnydale station and Balboa Park station.[20] Light rail service was re-replaced with buses on August 25 due to issues with malfunctioning overhead wire splices and the need to quarantine control center staff after a COVID-19 case.[21] Rail service resumed on the Embarcadero–Sunnydale section of the T Third Street line on January 23, 2021.[22] In preparation for the return of rail service, several temporary changes were made at the 4th Street bridge over China Basin: one southbound lane became a transit-only lane, and a northbound turn lane at Berry (which shared space with the tracks) was removed.[23] This change was found to decrease delays at the bridge by 60%.[24] Service was re-extended to West Portal on May 15, again through-routed with the K Ingleside.[25]
As part of the January 2021 service change, Muni also added the 15 Bayview-Hunters Point Express bus route. The route makes local stops in the Bayview–Hunters Point neighborhood east of Third Street and limited stops on Third Street paralleling the T.[26][27]
Central Subway
[edit]The second phase of the line was built as the Central Subway, which forms a crosstown link between South of Market (SoMa) and Chinatown via Union Square. Voters approved the Central Subway in 2003, and the alignment was selected in 2008.[28][29] Construction began in 2012.[30] After numerous delays, the Central Subway opened on November 19, 2022, with a weekend-only shuttle service operating between Chinatown and 4th and Brannan. The T Third Street was rerouted to travel through the Central Subway for full service on January 7, 2023.[31][32][33] Service runs every 10 minutes on weekdays and every 12 minutes on weekends. Shuttle trains signed "S Mission Bay" operate between Chinatown and UCSF/Chase Center for events at Chase Center.[34]
Station listing
[edit]All stations along this line feature high platforms, eliminating the need for the raising and lowering of entrance and exit steps characteristic of other Muni Metro lines.
