Curving Around

The temporary S-curve at the Treasure Island exit from the Bay Bridge westbound (2012)

The temporary S-curve at the western end of the east span of the San Francisco-Oakland Bay Bridge was needed while the new span was being constructed. In this December 2012 photo, you can see that the pavement is marked with a 40 mph speed limit. The left exit to Yerba Buena Island remained, though significantly modified as a result of the construction work.
