The second phase of construction for the Central Subway will start today, as tracks creating an essential link between Chinatown and the T-Third Metro line are laid.
Construction will begin at 10 p.m. and will end the evening of Saturday, Nov. 14.
The construction is the second phase in milestone construction linking the T-Third Muni train to its new segment, the Central Subway, which is set to open in 2019, according to the San Francisco Municipal Transportation Agency.
The linkage will create a key transit line between the Bayview, Mission Bay and Chinatown.
To facilitate construction, streets will be closed in the areas surrounding 4th and King streets, near the Caltrain station. To that end the SFMTA advises Caltrain customers heading downtown to take the 10, 30, 45, 81X or 82X Muni bus lines.
“Construction is going to be noisy,” SFMTA warned, in a statement. “The first few days of construction will include round-the-clock jackhammering and saw-cutting.”
Buses will also replace subway service every night for that week after 9:30 p.m. between Embarcadero and St. Francis Circle until 1:30 a.m. The weekend of Nov. 14, buses will replace N-Judah service between Ocean Beach and Church and Duboce from 5 a.m. Saturday until end of service on Monday, due to Sunset Tunnel construction.
The following streets will be closed for construction: Eastbound King Street between 5th and 3rd streets, southbound 4th Street between Berry and King, northbound 4th Street between the Channel and King streets intersection (locals will be provided access however), and the southern portion of 4th and King.
Traffic will be heavy for access to I-280, SFMTA warned.
