T Third Bus Substitution/UCSF Mission Bay Platform Project
Due to delays from weather earlier this year, another T Third bus substitution is needed to perform key construction tasks that must be done when the Line is out of service and de-energized.
The T Third line will be served by buses from Embarcadero to the terminal at Bayshore Boulevard and Sunnydale Avenue beginning Saturday, May 25 and lasting for approximately 10 days.
All Muni train stations between Embarcadero and the terminal at Bayshore and Sunnydale will be closed and buses will service all stops along 3rd Street, curbside. Customers traveling underground on Muni Metro towards Bayshore and Sunnydale will transfer to a T Third bus at Embarcadero. Please watch for signs that will direct you to the T Third bus shuttles.
T Third bus substitution details:
Start of service Saturday, May 25 for approximately10 days.
Like last time, a robust sign plan will be implemented in addition to ambassador support at key locations and at key times.
Other Muni service changes:
Street and traffic details:
- One lane in each direction will remain open on 3rd Street near the construction site throughout this phase.
Concrete pouring at two intricate rail sections, the single and double crossovers.
Replace overhead wires.
Electrical work on the platform.
Concrete pouring on the platform.
Completing installation of ad panels, windscreens and other platform tasks that need to be performed while the train is out of service.
Work will take place 24 hours per day in order to take advantage of the train’s absence and the need for de-energization of the overhead wires.
Note the UCSF Mission Bay Platform will be closed until the end of June 2019 continuing after the T Third bus substitution ends. Please use Mission Rock and Mariposa stations as an alternative while the T Third train is in service. Stay tuned for more details as we get closer to the opening of this brand new Muni platform.
