Rebar cage installation is complete and concrete will soon be poured for the roof deck of the future Yerba Buena|Moscone Station.

We made some changes to our weekly construction update.

This notice provides a construction update and a look ahead for what to expect in the areas where we are building four new stations along the alignment.  You’ll find work activities, traffic and transportation impacts over the next two weeks at SoMa, Yerba Buena|Moscone, Union Square and Chinatown.

Construction schedules, bus routes, and stop locations are subject to change due to unforeseen conditions.  Signs will be posted at affected stops to advise of service changes.

Starting Monday, June 8-July 3, the contractor will be performing work on the 36″ sewer line at the 4th and King streets intersection between the hours of 9a.m. to 3p.m. No through-traffic available on King Street to I-280. For more information, please see this notice.

On Tuesday, June 9 from 7p.m. to 5a.m., the San Francisco Water Department will be performing a pipeline tie-in work on Stockton Street between Jackson and Sacramento.

Our thanks go out to the businesses, residents, shoppers, commuters, and all those who are touched by the Project, for their continued engagement as we work to extend this city’s public transportation system.
