Came across a couple pictures of bridges over the same river in similar locations that're under the lake. Don't know enough about them to want to create new pages but figured I'd upload pics.
1915 Pit River Bridge LRN 3 Pacific Highway One of the several arched bridges originally constructed on the Pacific Highway, the first Pit River bridge opened in 1915. It was later submerged when the waters of Shasta Lake rose behind the dam. Chester photographed what could have been the arrival of dignitaries for the dedication ceremony. When the bridge was new and traffic was light, dances were held on the smooth concrete deck of the bridge.B 229. Photo from Shasta Historical Society
