Those planning to drive from the East Bay to San Francisco this holiday weekend will need to make alternate travel plans, as the bridge's upper deck will be closed starting Friday night to allow for construction work.
Caltrans spokesman Bart Ney said that the closure will allow crews to construct a detour near the toll plaza and to stripe lanes and place a guide rail along the route.
The detour carrying westbound traffic will shift traffic to the south of its existing path, making room for construction crews that need to demolish sections of the existing roadway that are in the path of the yet-to-be-built inclined section that will carry eastbound traffic from the new east span of the bridge.
The bridge's upper deck will be closed from 8 p.m. Friday until 5 a.m. Tuesday, although weather could delay the deck's reopening. Eastbound traffic, carried on the lower deck, will be unaffected by the closure. Vehicle travel between Treasure Island and San Francisco will also be unaffected, according to bridge officials.
Alternatives for crossing the Bay include taking BART, which will run overnight service at 14 stations during the closure, hopping a ferry from the East Bay or Vallejo, or taking the Richmond-San Rafael, San Mateo-Hayward or Dumbarton bridges.
