Moving further up the hill on A Street (to get above the trees and houses that are blocking the view that Patsy had), we can see that big dark bridge that was in several of her pictures from the 1930s. Apparently, that's the 1927 Carquinez Bridge (with a newer bridge to the left of it).
However, I'm not sure if the bridge we see on Google nowadays is the same one from Patsy's day. That one may have been torn down after it was deemed unsafe. The one that's still there now could be the second parallel bridge that was completed in 1958. Overhead view only shows 2 bridges there now.
Info from Wikipedia:
"The Carquinez Bridge is a pair of parallel bridges spanning the Carquinez Strait at the northeastern end of San Francisco Bay. They form the part of Interstate 80 between Crockett and Vallejo, California. The name Carquinez Bridge originally referred to a single cantilever bridge built in 1927, which was part of the direct route between San Francisco and Sacramento. A second parallel cantilever bridge was completed in 1958 to deal with the increased traffic. Later, seismic problems made the 1927 span unsafe in case of an earthquake, and led to the construction, and 2003 opening, of a replacement: a suspension bridge officially named the Alfred Zampa Memorial Bridge, in memory of iron worker Al Zampa, who played an integral role in the construction of numerous San Francisco Bay Area bridges. The Alfred Zampa Memorial Bridge carries westbound traffic from Vallejo to Crockett, and the 1958 cantilever span carries eastbound traffic."
