As Mission Bay gets built out, so is transportation infrastructure in the area to accommodate the greater demand.
San Francisco Municipal Transportation Agency board of directors on Tuesday approved a contract not to exceed $3.5 million with Mitchell Engineering to install tracks on the block surrounded by Third, 18th, Illinois and 19th streets to create a short loop for the Muni T-Third Street line.
The Mission Bay loop will allow the southbound light-rail line to turn left onto 18th Street, travel around the block on Illinois and 19th streets and make a right onto northbound Third Street. It will be a “critical component” of the central waterfront area and provide a short turnaround for trains once the Central Subway extending the T-Third line north to Chinatown opens in 2019, SFMTA spokesman Paul Rose said.
“The Loop would allow trains to turn around for special events (e.g. baseball games, concerts, street fairs) and during peak periods to meet the projected service needs in the Central Subway Corridor, including the Chinatown, Mission Bay and SOMA neighborhoods,” a staff report states.
Allowing half of the T-Third trains to turn around will not affect service for Hunters Point residents and others along the Third Street corridor because additional trains will be added to the turnaround route as part of the Central Subway project, the report details.
Mitchell Engineering is expected to complete construction within 240 days from a notice to proceed that comes shortly after the board's approval. A new arena for the Warriors and Uber's new headquarters are among developments coming to the area that have spurred the need to improve transit services.
