How to Use the New Bay Bridges (1939)

In 1939, Standard Oil of California (now Chevron) published a guide to the two major bridges across San Francisco Bay. Both the Golden Gate Bridge and the San Francisco-Oakland Bay Bridge were covered in the pamphlet. (The Richmond-San Rafael Bridge, linking Marin and Alameda Counties, hadn't been built yet.) Included in the small pamphlet was a map of the bridges, an explanation of how to get on the bridges, and some facts and figures about the bridges. The pamphlet is small enough that I was able to scan all of it at a size that easily lets you read the text.
