Never really paid much attention to the various bridges. Although, when the engine hits a red light, and the train stops to let some boat, ship, scow, to pass through, you get to notice how the bridge operates. My attention was riveted to a swing bridge going into the Rockaways, NY, over Jamaica Bay. The train stopped, at the horn blasting of the tugboat and barges, and the bridge swung around perpendicular to the tracks. The boat and its load then went through. I was fascinated by the trackwork leading, going through, and on the bridge. All sorts of interesting "pieces" stuck together to allow smooth passage and separation to allow the swing. A Mechanical Engineer's delight.

And a nightmare for the people in the B&B gang (and the signal maintainers) that had to keep it all running....

And the track guy's as well.  The miter rails can be very finiky about being exactly in proper position, and you better not let rail forces run into these things.  As a result a lot of time you need a rail expansion joint back a littl ways from these things on BOTH sides of the draw so that rail forces dont move the rail at these miter joints and cause them to jam up.    Saying rail expansion joint is a form of profanity for a track guy.

I can just imagine. There was a guy who had a draw-span on his layout in Austin at one time (it was raised to allow access to the layout - the door into the house was a sort of notional river...). He said he cussed some getting it working right. Pretty big bridge, a bit over two feet long so around a scale 175-180 feet at least.

Here is Bridge 5 on NS in Norfolk, VA The raised bridge in the background is the exVirginian Railway N&W passenger main that is no longer used. The train is S21, empties westbound on 6/27/10.

P.S. I was corrected about this bridge and was told it is still in place as an emergency backup in case something happens to the primary bridge.

This is the lift bridge over the Passaic River in Newark, NJ. Located just out side of the Newark Penn Station. Taken on 6/6/09.

Nice, it looks like the center abutment was where the swing gears were.

That's pretty sweet, having the bridge that close to the waterline... and another bascule bridge hiding behind it!

Isn't this down by the Nautica Pavilion? I saw a concert here last summer and was more taken with the bridge than I was with Ringo! There is also a mammoth stone RR abutment just south of here that dead-ends into space. I meant to research that but never did.

Who does the steel arch bridge belong to? Rail or highway?

The arch is a highway bridge, and yes, this draw is rignt near the Nautica Center.  On my tour a few years ago, they called this a jacknife bridge.  There are a couple more disused RR bridges crossing the Cuyahoga.  The next bridge in the background is a swing bridge with no center span, it pivots from the shore.  It's not a RR bridge, tho.

Excellent! Thanks man. Do you know anything about the stone approach/abutment by chance? Maybe a 1000' south of Nautica?

Looks like the bascule draw bridge on the Galveston causeway (a single-track structure that replaced the original 1912 three track bascule not that long ago) is not long for this world. Appears that the 125 (approx) foot bridge, over a 105-foot channel on the Intracoastal  Waterway will be replaced with a lift bridge some 200 feet longer, thus remedying what is considered by the USCG the most dangerous current spot on the ICW.  
 
Piers, towers and deck-girder connections to existing track will be constructed beside the present structure and when all is ready, the new bridge will be floated out and put in place. Old span will be demolished and one or more arches removed (apparently on the north - mainland - side) and the track connections made and (presumably) ICW channel dredged to take advantage of the new width.
 
Guess will have to take another trip don to Galveston and see the new bridge once it is in. Pity there isnt passenger service to the Island so could ride across it....
 
EDIT - appears that structure will be removed on both sides of the current channel and the channel widened  very significantly. Should put an end to people running into the causeway - but I bet it doesn't....

The one at Galveston will look a lot like that one, except will be on foundations in the waters of Galveston Bay.

Union Pacific's Baring Cross Bridge, a double track vertical lift bridge over the Arkansas River in Little Rock. One of three vertical lift bridges within a mile of each other in the downtown area.
