Description 

"The one lane pony truss bridge carries Mountain Road over one line of Raritan Valley Line track. Originally two lines of track were crossed. It is located in a wooded sparsely settled area, immediately adjacent to an intersection." [ there are 2 lines of track there presently ]

"The cambered ten panel Warren with verticals pony truss bridge is riveted. It is supported on concrete abutments and wing walls. The curved top chord is a built-up box member. Outriggers are original. Lacing on diagonal members is riveted to the outside edge of the angle. Alterations are minimal. Strengthening plates have been added to the bottom chord. Stringers and deck are replacements. The NJ Transit Historic Railroad Bridge Survey recommended that the bridge be ineligible."
