Mission Bay Loop
The proposed Mission Bay Loop is a component of the T Third Street line and Central Subway Projects and located within the Central Waterfront area on the blocks of 18th, Illinois, and 19th Streets. The loop would allow trains to turn around for special events and during peak periods to accommodate additional service between Mission Bay and the Market Street Muni Metro.

The proposed Mission Bay Loop (MBL) was designed in 1998 as part of the Third Street Light Rail Project, completed in 2003. An Environmental Impact Statement/Environmental Impact Report (EIS/EIR) for the Third Street Light Rail Project was completed and approved in 1999 by the Federal Transit Administration (FTA) and the City and County of San Francisco. Yet, due to budget constraints, construction of the MBL was deferred.
Approximately fifteen years have passed since the EIS/EIR for the Third Street Light Rail Project was completed. Now, the project has secured funding under a partnership with the FTA for allocation of $10m TIGER funds through the Department of Transportation (DOT) and the Lifeline Transportation Program from the Metropolitan Transportation Commission (MTC). Additionally, the FTA prepared an Environmental Assessment (EA) report to identify and evaluate any conditions that may have changed after 1999 that could potentially result in adverse environmental effects from construction and operation of the MBL.
The proposed Loop would be constructed in the Central Waterfront area of the City and County of San Francisco, on city roads and rights-of-way on the blocks of 18th, Illinois, and 19th Streets. The existing trackway on 18th and 19th Streets between Third and Illinois Streets would be extended to Illinois Street to complete the Loop. Traffic, pedestrian, and train signals would be installed at the intersections of 18th and Illinois Streets and 19th and Illinois Streets.
The Loop would provide turn-around capabilities for the T Third Street light rail line via a connection of trackway from Third Street to 18th, Illinois, and 19th Streets. Also, the MBL could remove disabled trains and provide a means to turn trains for special events and during peak periods to accommodate additional service needed between Mission Bay and the Market Street Muni Metro.
Moreover, the MBL is integral to the Central Subway Project due to increasing population growth in the southeastern quadrant of the City and the expectation to accomodate ridership demand to transit connections and destinations such as Caltrain, BART, the Financial District and the Chinatown area.
