That trestle doesn't even have tacks on it (There are two tracks next to it on a new trestle that are active, but you are far enough away to not have to worry about them. The trestle it's self is well over 100 years old. If you walk across it you can feel how loose the ties are, but they are so thick and the bridge is so well constructed that I have no fear of crossing it.
There was an old town called Hampton in the area. Besides a few sidewalks, some spill damn bridges and some foundations, you would never know it.
