ONGOING: UCSF Mission Bay Arena Platform Project

In anticipation of the new Golden State Warriors’ Chase Center and growth in the Mission Bay, the SFMTA is constructing a new center platform along 3rd Street between South and 16th streets. This new, larger platform will service both inbound and outbound trains and greatly expand transit capacity in preparation for large crowds.

For detail information and to sign up for email updates, visit https://www.sfmta.com/projects/ucsf-mission-bay-platform-upgrade. The UCSF Mission Bay Platform is now out of service through late April 2019. The T Third will continue to operate but will skip that stop.

Work will occur just north of the bridge in the two eastern lanes. Emergency repair work is not anticipated to cause additional impact to traffic in the area as work will be within an area that has already been closed off to traffic during the first phase of bridge rehabilitation work. Emergency repairs are anticipated to be completed by Friday, January 18.

Now through January 2020: Crews have begun Phase Two of the Third Street Bridge Rehabilitation Project. For more project details, visit: http://www.sfpublicworks.org/thirdstreetbridge.
