What?
The Transbay Joint Powers Authority (TJPA), through its contractor Cal Vada, will be conducting a land survey along the entirety of the future underground rail alignment between the intersections of Townsend & 7th and Howard & 2nd. This important work is part of the TJPA’s The Portal, also known as the Downtown Rail Extension, to extend Caltrain commuter rail from its current terminus at Fourth and King streets and to the TJPA’s multimodal Salesforce Transit Center’s already built two-level trainbox in downtown San Francisco.

Where, When and What Time?
On both north & south sides of Townsend Street between 7th Street and 2nd Street, and on the east & west sides of 2nd Street from Townsend north to Howard. The surveyors will progress from Townsend Street east toward 2nd Street, then north on 2nd Street toward Howard.

Approximately two months of work from Monday, August 4, 2025, through Friday, September 26, 2025 from 7:00 a.m. to 4:00 p.m. (Note: Due to unforeseen circumstances, this schedule is subject to change without notice.)
