SAN FRANCISCO (CBS SF) — Commuters who use Caltrain, Muni or drive through San Francisco’s Mission Bay neighborhood should plan ahead as Central Subway construction will impact Fourth and King Streets for eight days starting Friday.

According to the SFMTA, Eastbound King Street between Fifth and Third Streets, Southbound Fourth Street between Berry and King and Northbound Fourth Street between Channel and King will be closed starting Friday night at 10:00 p.m.

Construction at 4th and King is expected to be finished on Saturday, November 14th at 11:59 p.m.

Workers will be installing track connecting existing rail lines to the Central Subway.

Several Muni Metro lines will be impacted. Buses will replace trains on the T-Third line between Sunnydale and Embarcadero during the closure, the SFMTA announced. The N-Judah line will stop at a temporary platform on King between Third and Fourth, while the K-Ingleside will run between Balboa Park and Embarcadero stations only.

SFMTA said Caltrain riders who use the 81X and 82X lines can board from a temporary stop on Townsend between Third and Fourth.

A full list of Muni-related impacts has been posted on the SFMTA website.

Drivers should expect significant delays near 4th and King. Traffic will be diverted off the Interstate 280 / King Street off-ramp at Fifth Street, and Berry Street will become a one-way street going eastbound between Fifth and Third.

The Central Subway is expected to open in 2019.
