I finally found a photo of the original swing bridge in the book: Historic Highway Bridges of California, published by, California Department of Transportation, (out of print). The original bridge was replaced by one of the most uninspiring movable bridges I have seen in this region.
I would love to have a picture of the old bridge. To me the value of this entire website is the photographing of the old bridges before they are replaced. Sometimes we are late. I have only been capturing bridges at an accelerated pace for two years now and already I know of two bridge I have shot that are being replaced during 2010. The race is on to capture before they are gone.
To bad that's a picture of the new bridge!
