Grantville Road Bridge
Forlorn and abandoned in upstate New York sits one of the longest single span lenticular truss bridge ever constructed by the Berlin Iron Bridge Co. Even by modern standards its 288 foot length for a single span is still notable, but by contemporary standards this must've been nothing short of majestic.
Built in 1886 for $10,000, this is pretty standard in some respects as it has ornate portal cresting and an elegant builders plaque, as well as cast iron finials. In a departure from the standard design the internal webbing of the truss is patterned on a Warren truss instead of a Pratt truss, which Berlin Iron Bridge Co. used for its longest spans. Also unique to the Warren webbing are the floorbeams resting on a lower chord, which is in turn suspended from the truss (as opposed to the standard design where the floorbeams are directly suspended from the truss
The bridge was closed to vehicular traffic in 1979, but continued to be open to pedestrian traffic for a few years before being completely closed. Despite having been out of service for such a long time the bridge continues to be very solid and retains an exceptional amount of historical integrity.
Part of the deck on the western side of the bridge has been removed (and is fenced off with salvaged original railings!), and the wooden pedestrian walkway is thoroughly rotted, but otherwise this bridge is still safely cross-able and still completely savable.
