B&LE = Bessemer & Lake Erie
The only other 4-track swing bridge I have seen carried the route to Grand Central Station over Harlem River in NYC.
While researching the Ashtabula Bridge disaster, I discovered this bridge. And it still exists! But one of the tracks has been replaced by an access road. The Bridge Hunter description indicates that it is still operable.
