Alder Point Road Suspension Bridge
Posted October 15, 2019, by Mike Brady (mikebrady60 [at] yahoo [dot] com)

Saw it at about 6:30 in this video (from 1960s 8mm film), from the railroad: https://www.youtube.com/watch?v=N-Rq8SwvxpA

Wondered what it was, since small-road suspension bridges are rare. Some people at a railfan site identified it.

Might be able to do a frame cap, but no guarantees re. quality.

Bridgemeister states:

The Sunday November 5, 1972 edition of The Times Standard (Eureka, California) has three photos of the bridge collapsing. The caption is "Old Alderpoint Bridge Crashes into River." It continues: "Cables, securing the old Alderpoint Bridge across the North Fork of the Eel River, were cut Friday to send the structure splashing to the feet of the new concrete span that is replacing it. The $1-million new bridge was dedicated Saturday. The old suspension bridge was constructed in 1917."

does anyone have access to that? Especially the pictures.

I remember when this bridge replaced a single lane through truss bridge over the river. I was sad to see the old one go.
