Still in Bainbridge but a few hundred yards south is another Flint River swing span on CSX's north-south line that was formerly the Seaboard mainline to Columbus GA.

Have noted the bridge over Mantua Creek in New Jersey involved in the recent derailment and HAZMAT release (vinyl chloride) is an unusual swing bridge. Single span, pivot is off the line of the track so it is like a shelf with track on it, with hinge at one corner. Friend and I built one much like it (with no idea it had a prototype on a rail line) to allow his layout to operte across a door without having a duck-under. Seems there is a prototype for any thing...

The Long Bridge over the Potomac River has a swing span portion. Here we see Amtrak train #20, AKA the Crescent, crossing the CSX bridge into Washington DC. at 0938Hrs on 2/12/13.

This bridge has not been opened in years.  The joints in the rails have long since been taken out.  Don't know whether the machinery is still in place or not.  Although not a railroad bridge, the Arlington Memorial Bridge has a draw span in it, again not used in years.  The 14th street bridges in between them, and the Metro bridge do not have draw spans.

Ok, thanks for the correction. Seems a lot of bridge structures that at one time opened for water traffic no longer do that. This one, however, seems to still be in use. The ex-PRR bridge over the headwaters of the Nanticoke River in Seaford, DE on 6/26/13.
