I noticed that Cleveland has quite a few lift bridges for roads as well as railroads. After Chicago built the Halsted Street Bridge, they decided lift bridges would be too ugly for use in the downtown area so the invented their Chicago Style trunnion bascule design.

Bridge Hunter has a build date of 1947. But Historic Bridges explains the project to widen the river was started in 1946, but this bridge was completed in 1958. C Hanchey's Flickr page also uses the 1958 date. I assume the truss on top carry pipes.

(new window) You can tell it is a more modern bridge, the train is going pretty fast for a movable bridge. Fast train speeds would be important for Norfolk Southern and Amtrak since this is on their mainline between Chicago and New York. At 3:21, at second train crosses the bridge. At 4:46, the trains are done and the span starts to lift.

Paul VolosynCool seeing one come off the Clark branch and heading west on the Chicago line. Also the B&O coming across bridge 464 (by shooters) and heading to the interchange with the NYC. Great photo.

(new window) At 3:00, it sounds like the ship has a steam engine. Only the first two scenes are at night. At 6:20, Hulett unloaders are in the background! 7:49 shows the rolling bascule bridge. In the foreground at 10:59 we see how jointed rail becomes wavy if it is not maintained. At 12:32 you realize he has been riding up with the span.
(new window) Note when it raises at 3:57 that this bridge has very little clearance. Even small pleasure boats have to wait for it to go up. Even ski- jets and kayaks?

( Bridge Hunter ; no Historic Bridges; Bridge & Tunnels ; HAER ; Satellite ) WNYP = Western New York & Pennsylvania Railroad (leased from Norfolk Southern) This bridge carried Pennsy's mainline between Pittsburgh and Buffalo. Most of that line has been abandoned, but one of the original two tracks that were on this bridge is still used by the WNYP. Photo from HAER PA,61-OICI,2--2 from pa1273 July 1971.

( Satellite , three slips allowed them to make six ships at a time because they were launched sideways.) Later, they switched to fewer, but bigger ships. They were built in a dry dock and then floated out. Pete Martin posted My grandfather in drydock 2 at shipyard. Prob 1966.
