During the 1840's, the Delaware & Hudson Canal was looking at ways to speed up service along its route. One of the major bottlenecks was where the canal reached the Delaware River. Since it began operation in 1828, the D&H used a rope ferry to pull traffic along to Canal across the Delaware. The conflicting traffic of vessels going down the Delaware to Trenton or Philadelphia and of the coal freight cutting across the river on the canal created great bottlenecks. That is in addition to the difficulty ferry operators would have fighting the powerful current.
In 1847, the D&H commissioned John A. Roebling to construct a suspension bridge that would carry canal traffic above the Delaware. In comparison to then-contemporary designs, Roebling's suspension design allowed for more room for downriver traffic and the dangerous ice floes to pass through. Two years later on April 26, 1849 at a cost of $41,750, Roebling's Delaware Aqueduct opened to canal traffic. Soon thereafter, a sister suspension aqueduct, the Lackawaxen, was opened nearby at a cost of $18,650. (1) The two bridges' impact were immediate and impressive as canal traffic was shortened by one full day. The D&H was so impressed by the success and the bottom-line impact of the two bridges that they commissioned Roebling to design and construct another two. Two years later, Roebling finished the construction of the Neversink and High Falls Aqueducts in New York.
Eight Decades of Neglect (1901-1980):
As railroads grew throughout the country, the need for canal traffic drastically declined. In 1898, the D&H ceased operations. Three of the four aqueducts, Neversink, High Falls, and Lackawaxen, were dismantled. The Delaware, which still had a great deal of practical purpose as it crossed a major river, was sold to a private owner. The owner, Charles Spurks, used the now dry aqueduct to haul logs for his lumber company across the bridge. He built a toll house on the New York side of the river charging a toll to all others on the crossing.
The bridge would change hands several times during the next 70-plus years. As ownership changed, the condition of the bridge deteriorated. The towpaths were dismantled, replaced by a handrail. In 1933, the trunk of the bridge burned away completely. Only the bridge deck was replaced, the walls of the aqueduct were not replaced. A near tragedy occurred in 1977, when a truck fell through the bridge. A lawsuit was filed against the then owners, but the bridge was only closed temporarily. The condition of the bridge deck was so bad that one member of the park service said, "All one had to do was hop up and down on one end, and I could see a ripple running all the way from Pennsylvania to New York." (2) In 1980, the National Park Service bought the bridge and closed the structure in the hope to restore it.
Once the National Park Service owned the aqueduct, discussions and planning began on how to restore the bridge. Before the bridge was under the Park Service control, the bridge was deemed in 1968 to be a National Historic Landmark. In 1983, testing began on the strength of the bridge, and amazingly Roebling's original provisions easily met modern standards. With most of the original superstructure intact, restoration began in 1985. The restoration of the superstructure's base to Roebling's original specification was complete in 1986. In 1995, the aqueduct walls, towpaths, and wooden icebreakers at the base of the piers were completed.
Today, the bridge is again open to vehicular traffic, without tolls. It is a one lane bridge, and the former towpaths serve as sidewalks. The toll house on the New York side remains and now serves as a history center detailing the history of the aqueduct, the D&H Canal, along with the restoration process. With all original features of the bridge restored, crossing the bridge is like going back in time; the only difference, you don't need a boat to cross it.
