One of the Great Wonders of San Francisco: The Bay Bridge


Daily hundreds of commuters commute across the bay bridge from communities ranging from Berkley to Concord. However many people just see this as a bridge and few truly appreciate the magnificence of this wonderful structure.

Also even fewer realize that they can find so much about projects and other fun facts about the Bay Bridge on http://baybridgeinfo.org/ and for video coverage go to http://baybridge360.org/#/section/sastransitions.

As you may know there are many reconstructions going on around and on the Bay Bridge. Most of the work is centered around the Yerba Buena Island Transition Structure (YBITS) and the Self-Anchored Suspension Span (SAS).

According to the Bay Bridge info website, the SAS section of the bridge is currently under the largest public contract in California history. The renovations' main job is currently to re-enforce the bridge to make it better structured in the case of an earthquake. This section of the bridge is the largest bridge of its kind and is quite unique in the way that it only has one support cable attached the a 525 foot tall steel tower, along with many other tiny cables.

On the YBITS section of the bridge the state is adding a 900 foot parallel expansion/detour.

  1. What a beautiful image. I wonder if the the photographer or the website producer changed it in Photoshop? I've seen a purple sunset in San Francisco, but I've never seen the bay that hue.
