BRIDGE HISTORY

The first bridge at Lumberville was built in 1856. The original span over the river was washed away by the flood of October 10, 1903. This span was replaced in 1904 by a steel through truss bridge.

The upstream nose of Pier #2 was rebuilt in 1943. At this time, it was determined that the entire bridge superstructure, except the steel span, was in poor condition. In 1947, the entire superstructure was demolished and removed. The substructure of the original bridge is still standing today and now supports the present pedestrian crossing. John A Roebling & Sons Company constructed the bridge. The new suspension structure used 50 tons of structural steel. The bridge had only minor damage during the flood of August 19, 1955.

BRIDGE STRUCTURE

The anchorage on the New Jersey side of the bridge shows five cables providing support to the bridge.		There is 1390 feet of chain link hand railing on the sides of the bridge.
Cable structures are shown here.		This shows the details of the cable support system.
The webs are trapezoidal in shape.		Cables pass over five towers supported on piers (four of which sit in the water).
All piers and abutments are constructed of rubble stone masonry shells with a loose stone-filled core.		The entire bridge deck was reconstructed with precast "waffle slab" sections in 1993 after significant deterioration in the original concrete walkway.
