We also have CSAA's "North Bay Counties" from 1946 which is good for comparison. We don't own any Thos. Bros. maps of that area from that time period, but numbering of roads is marked better on them than on the CSAA maps. I took a look at the "Carquinez" 1:62,500 topo, but the edition of 1901, reprinted 1926, is too early for your purposes, and doesn't even show the ferry. The subsequent edition of that topo is 1942, much too late. You could check for an edition in between, then find it online if there is one. How about nautical charts showing the Carquinez Strait?

I have helped him with the Utah section, and now he has contacted me looking for information on the route in California, particularly in the Bay Area. He has seen a reference that it once passed through Martinez and Crockett in Contra Costa County. He was hoping I’d have a map from the 1920s that might show the designated route, but I do not. Our library’s Special Collections has some guide books with strip maps for Utah and adjacent states, published by the Utah State Association Touring Bureau and Auto Club Bureau of Information (probably predecessors of AAA chapters), and maybe similar guides exist for the California stretch. My best guess is that, when U.S. 40 was designated in 1925, it was routed through Benicia to a ferry crossing the Carquinez Strait to Martinez and then followed a route west to San Pablo Avenue, which was certainly U.S. 40 later on. When the first Carquinez Bridge was built in 1927, they rerouted the official highway over it. So the key is to find a road map showing U.S. 40 during the two-year period between designation and rerouting. Maybe one of your collections out there (library or private) includes such a map and you could look this up for us? A copy, paper or scanned would be wonderful if such a map is found.
