Description 

Abandoned timber stringer bridge of an unknown age carrying a former alignment of Coteville Road over the Derry Rail-Trail corridor. The bridge has clearly not been maintained for a substantial amount of time given the condition of the superstructure and the deck. Coteville Road currently dead-ends at the bridge, with signage posted reading "Danger - Keep Off Bridge". The Rail-trail corridor is passable on foot or bike up to the bridge from the north, but is not passable south of the bridge due to excessive illegal dumping as well as a washed-out bridge over Beaver Brook located south of Coteville Road.

This design is super common for railroad overpasses. One of the "If it ain't broke, why fix it? designs that were the common choice for rural crossings until rather recently.

If not plain timber stringers, it would be a timber stringers augmented with relocated railroad bridge spans. Typically lightweight/outmoded pony trusses and through girders.

John Marvig has documented several for the site.

Nick: You have to use "Try to find in NBI" for anything prior to the latest listing; this bridge remained listed up until 2017.

Going through BridgeReports will only give you the latest (2018) listing.

Luke: I was not able to locate this bridge at BridgeReports.com - where did you find the NBI data?

A 1942 build date actually seems a bit young/early to me given my observations - it looked like a structure that dated back to the original days of the railroad.

George, as I noted in my other post, the photo credit line already states when he took the photographs. Him re-stating what has already been stated in the comments is redundant/superfluous.

The photos already say "Photo taken by Nick Boppel in April 2020", so don't you think your comment is a bit superfluous?
