NEW: UCSF Mission Bay Arena Platform Project

In anticipation of the new Golden State Warriors’ Chase Center, the SFMTA is constructing a new 320-foot center platform along 3rd Street between South and 16th streets. The existing platform will be demolished. The new track alignment will include one single and one double crossover to facilitate the movement of vehicles as operations requires. Other associated work includes modification of the overhead contact system, and both above and below ground utility relocation work. Construction will require four phases that will necessitate three separate transit service plans.

Buses will provide T Third service from Tuesday, January 22 through March 2019 in order to accommodate the next phases of construction. Once the T Third returns to train service, the Muni platform at UCSF Mission Bay will remain out of service through late April 2019. The T Third will continue to operate but will skip that stop. Customers should board at Mission Rock and Mariposa stations.

E Embarcadero and 83X Mid-Market Express will be temporarily canceled from Tuesday, January 22 through March. Alternative routes include 47 Van Ness for the 83X and the N Judah and F Market & Wharves for the E.

55 16th Street will be rerouted onto 4th Street starting Tuesday, January 22 through mid-February in order to accommodate the construction zone.

3rd Street between 16th and South streets will be closed northbound and down to one lane southbound starting Tuesday, January 22 through mid-February. For more information, visit
