I don't recall seeing anyone posting this one, so just in case:
Starting at sunrise on Tuesday, September 13th, a mid-span portion of the East walkway on the Golden Gate Bridge will be closed to pedestrian traffic to allow seismic retrofit work to continue. According to the Bridge District, during the approximately four month closure through mid-January 2012, pedestrians will NOT be able to walk all the way across the Golden Gate Bridge. From the San Francisco (southern) side, pedestrians will be able to walk out roughly 1.4 miles before having to turn around; from the Marin County side they'll be able to walk out 700 feet. Access from the San Francisco side is far enough to allow pedestrians to get to the south and parts of the north towers of the bridge.
The good news is that starting on September 10th, the west walkway on the Bridge will be reopen to bicycle traffic. Bicycle riders, some of whom are cycling across the bridge as part of their commute, rather than a one-off pleasure jaunt, will be able to completely cross the bridge from Marin to San Francisco or vice versa using the west walkway 24/7. From 7 AM to 3:30 PM weekdays riders will, however have to dismount and walk their bikes for a 400 foot stretch mid-span, because of a narrowed walkway.
