The Pacific Electric Fletcher Avenue Bridge in 1959.
From Ralph Cantos:
By 1959, the Fletcher Dr Trestle had become a liability ,young kids throwing rocks off the bridge onto passing autos below, and in some cases, daredevil motorists driving their autos over the bridge itself. The City had enough, and the bridge was taken down. This image shows the bridge in 1959 just before the end. It had been abandoned for almost 4 years.
