Golden Gate Bridge west sidewalk closed for 4 months starting Tuesday
The entire length of a Golden Gate Bridge sidewalk will close for several months starting Tuesday for a retrofitting construction project, bridge district officials said.
The entire west sidewalk will close Tuesday and remain closed through September as part of a seismic retrofit construction project. Bicycles and pedestrians will share the east sidewalk, with 24-hour access for bicyclists and sunrise-to-sunset use permitted for pedestrians, bridge officials said. The construction work also involves replacement of the roof of the Marin Anchorage Housing.
Come September, construction will move to the east sidewalk, but only a 300-foot section will be closed for four months into 2012.
The sidewalk closure is part of a third phase of a three-phase bridge retrofit project. The first two phases were completed in 2001 and 2008, respectively, according to bridge authorities.

During the project, workers will be removing old chipped concrete and adding steel to the bridge to make it more structurally sound to withstand earthquakes.
Most of the activity will be during the day underneath the bridge on Troll Avenue between 36th Street and Lake Union. Workers will close one block at a time and fence off some parking so pedestrians and cars don’t get hit by construction debris. Other than the localized traffic and parking issues there shouldn’t be any significant impacts.
This $5.7 million project is funded by the 2005 gas tax.
