The Bridge

Hello, and welcome also! I responded to your note on the talk page (now at the bottom). I had "eyeballed" it at 115' at N end of main span and 118' on S end, which fits with your figures. I chose 115' as it was the minimum distance vehicles would have fallen to the water. I didn't feel we needed the level of detail in the former footnote (especially as no one was challenging it) but would not oppose it.

I think what the article really needs is a description of what the bridge is. True, it is a deck truss, which simply means the deck is atop the trusses, not below or between them. But it was also a cantilever, with the outer arms of the main spans balancing the "arch" over the river. Unlike a true arch, the thrust is not transmitted outward to abutments, but down to the piers, as in a cantilever. When the center span fell, the north main span rotated backwards as shown on the video, as its weight was no longer counterbalanced. But without attribution, we can't say it's a cantilever. If you come across anything on that, please add it. Thanks, and welcome again. Kablammo 00:12, 13 August 2007 (UTC)[reply]
