The San Francisco Municipal Transportation Agency (SFMTA) is constructing a new, larger center platform along Third Street, between South and 16th Streets, in anticipation of the new Golden State Warriors’ Chase Center opening, and the future growth of Mission Bay. This upgrade will greatly expand transit capacity in anticipation of the Chase Center opening later this year.

Residents and visitors who would use the T Third route will instead travel by bus. This change, which will carry through March, is taking place to allow for construction on the platform and train tracks. Ambassadors and signage will help guide customers during the temporary shift from train to bus. One lane of traffic on Third Street will be closed in each direction during this time. SFMTA expects the new platform to be fully operational by late April.

T-Third Bus Substitution Route Information

UCSF/Mission Bay Construction

Changes customers should note during the bus substitution include:

  • K Ingleside trains will operate from Balboa Park to Embarcadero Station
  • T Third buses will travel from Spear at Market to Bayshore Boulevard at Sunnydale Avenue
  • Customers traveling on Muni Metro with a destination toward Bayshore and Sunnydale should transfer to a T Third bus at Embarcadero Station

Buses will service all surface stops. Some stops will have modified locations due to construction activities.

This phase of construction is expected to be completed by February 8th, 2019.
