Comparison of 1930 sketch of Bay Bridge tower versus 1935 construction photo of tower 5 as built.
<a href="//commons.wikimedia.org/wiki/User:Binksternet" title="User:Binksternet">Binksternet</a>: I put together this new, original image which is a comparison of portions of two other images from different sources. The left half is from a drawing included within the 234-page Hoover-Young Bay Bridge Commission Report (a federal project which was completed in August 1930), and the right half is cropped and reduced from a 1935 construction photograph showing engineer Purcell and others standing on the pier of a tower to the west.
