SR 1011-470 Pond Eddy Bridge over the Delaware River, Bridge Replacement

Shohola Township, Pike County, Pennsylvania and the Town of Lumberland, Sullivan County, New York

SAI performed final design and construction consultation for the total replacement of a historic two-span truss bridge over the Delaware River. The new structure, which mimicked the original bridge in appearance, was constructed upstream and parallel to the existing structure while recreational use of the river was maintained at all times.

Physical Features:

  • 506′ two-span steel Pratt truss bridge over the Delaware River.
  • Substructure units consist of reinforced concrete cantilever abutment founded on steel H-piles (NY Abutment); reinforced concrete drilled caisson wall (PA Abutment); and a reinforced concrete wall pier founded on steel H-piles.
  • 1,151′ of total roadway approach reconstruction in PA and NY.
  • Deck includes one 15′ 8″ lane with a 5′-0” sidewalk totaling 10,500 SF of deck area.

Other Features:

  • In-depth public involvement including formation of Design Advisory Committee (DAC); continuous community outreach through meetings, newsletters, and a website; and development of a 3D bridge model for visualization at public meetings.
  • DAC commitments included new structure to consist of a two-span truss with masonry architectural treatments on the substructures and paint color to match surroundings; installation of an interpretive sign (historic marker) to commemorate the original bridge; and archaeological monitoring for all excavation in NY due to presence of historic canal.
  • Significant site access and constructability issues with no available construction access through PA. Eight (8) stage full-width causeway constructed from NY stream bank required placement of more than 35,000 CY of rock in the river.
  • Construction staging/techniques allowed continuous use of Delaware River by boating community and local liveries (rafting/canoeing businesses) through implementation of complex ATON Plan.
  • Site located within National Park, requiring permits and authorizations from NPS, USACE, DRBC, PADEP, NYSDEC, and USFWS, among others. Restrictions in-place for Shad/Eel, Freshwater Mussels, Bald Eagles, Federal Wild and Scenic River, and PA Water Trail.
