  • current bridge is the third built at this location
  • idea first surfaced in 1853, but first bridge (old rounded Bow Truss style) not built until 1870 for wagons and passengers at the cost of $50,000
  • second bridge (Warren Truss style) built in 1901 to accommodate trolleys, other vehicles, and pedestrians
  • second bridge strengthened in 1923 due to larger and heavier trolleys

  • construction of present bridge (through Pony Truss style bridge) began in 1934 as a partially federally funded Public Works Administration project
  • in February, 1935, design and construction problems identified; operating machinery for the movable span was under water at certain high tides. Construction differed significantly from prepared contract plans. 
    • swing span was required to be raised 4 feet and abutments 3 feet to overcome this problem
    • bridge approaches were also raised to meet the new elevation
    • Burlington County Freeholders replaced Bridgeweld Engineering Corporation (of NY), the original Consulting Engineer
    • Ash, Howard, Needles, and Tammen (of NY) appointed new Consulting Engineer
    • revised as-built contract plans were forwarded to the US War Department for approval
  • opened to traffic on September 14, 1935
  • officially dedicated as the “Landon-Stone Memorial Bridge”
    (Landon and Stone were Burlington County residents who served as high-ranking officers in the Spanish-American War and World War I)
  • general contractor was Kolyn Construction Company
  • fabricator and erector of the superstructure steel was the American Bridge Company


  • total cost was $252,000
  • in 1966, ownership and maintenance transferred from Burlington County to the Burlington County Bridge Commission because bridge and the road (County Route 543) acted as a "feeder" to Tacony-Palmyra and Burlington-Bristol Bridges
  • no tolls are collected from bridge users
  • no tax money from Burlington County residents is used to maintain this bridge

1935: Riverside-Delanco Bridge officially dedicated as the “Landon-Stone Memorial Bridge” — bronze dedication plaque

  • structure consists of 3 through Pony Truss spans
  • center 160-foot movable swing span rotates horizontally to permit the passage of recreational marine traffic
  • total length from abutment to abutment is approximately 394 feet
  • roadway is 36 feet wide and carries 2 lanes of vehicular traffic
  • pedestrians can travel across the creek on the downstream side of the bridge


  • vertical clearance under the swing span is approximately 12 feet at low tide and less than 6 feet at high tide
  • marine vessels requiring a vertical clearance greater than that of the movable span in its normally closed position must request a bridge opening. The swing span rotates 90º over the center pier and fender system to permit passage of the vessel; vehicular traffic is temporarily stopped until the vessel clears the bridge; the span then resumes its normal lowered position.
  • opening and closing operations occur at the center of the swing span, at roadway level, by the bridge operator
  • horizontal navigation clearance at the swing span is approximately 52 feet between the timber fenders


  • electrical power is supplied by PSE&G. Submarine cables installed under the riverbed carry power from one side to the other
  • navigation lights installed at various locations warn the marine traffic of the bridge structure



1870: First bridge built was the old rounded Bow Truss style


  • concrete deck and approach pavement surfaces were initially repaired and resurfaced in 1966 and then again in 1997
  • original pedestrian walkway was replaced in 1994
  • bridge still has its original deck which has been diligently repaired over the years
  • numerous structural steel and concrete repairs were performed in 2000
  • completely repainted in 2001
  • custom carved wooden bridge identification signs were installed on both ends of the bridge and historic-style light poles and twin luminaries replaced existing standard aluminum light pole assemblies in September 2000 (in recognition of bridge’s 65th anniversary)

Service Times

  • remains in service to the public through all kinds of weather and conditions
  • from November through March, although no full time bridge operators are on site, with 24-hour advance notice the bridge can be opened for any mariner
