The 2010 rehabilitation is covered at http://www.historicbridges.org/bridges/browser/?bridgebrowser=newjersey/rockefellowsmills/
along with numerous "before" pictures. While the renovated bridge is no longer 100% original (new railings and floor beams) it is 5 times stronger than before, going from a 3 ton rating to a 15 ton rating.
This bridge is also a bit atypical for the area, with a single span of nearly 140 feet. Most other old bridges in the county are two span ponies for that width. The A-frame portal bracing is the only sway bracing on the bridge. There is none where the verticals meet the top laterals, although such bracing is not at all uncommon on through trusses in the area.
This bridge is almost exactly the same as the Fryer's Ford bridge that collapsed. Same builder, same age. Much better cared for. http://bridgehunter.com/ar/conway/fry/
Nice photos, Andrew! And I appreciate the text that's with them.
On the photo "another view below", those lateral pieces between the outer two strigers (joists) are called diaphrams. No, I don't know why. *smiles*
This looks like a first-rate rehab. Stainless steel pins. Railing not attached to verticals. The parts above the deck look authentic.
It is no longer historically authentic - but it is now a useable part of a modern highway system.
