Study Finds 14 Deficient Bridges on Long Island

According to an article recently published in Patchogue Patch, written by Paige McAtee  it identified 14 bridges on Long Island that were deemed structurally deficient based on the State transportation departments report that has identified 56,000 structurally deficient U.S. bridges overall.

According to the report quoted within the article:

  • Of the 17,462 bridges in New York, 1,928, or 11 percent, are classified as structurally deficient and possibly unsafe. This means one or more of the key bridge elements, such as the deck, superstructure or substructure, is considered to be in “poor” or worse condition.
  • 4,531 bridges, or 26 percent, are classified as functionally obsolete. This means the bridge does not meet design standards in line with current practice.
  • 884 bridges are posted for load, which may restrict the size and weight of vehicles crossing the structure.
  • Federal investment in New York has supported $17.5 billion for capital improvements on 3,481 bridges between 2005 and 2014.
  • Over the past 10 years, 1,290 new bridges have been constructed in the state; 623 have undergone major reconstruction.
  • The state has identified needed repairs on 12,386 bridges, which the state estimates will cost $75 billion.

  • Colonial Road Bridge in Great Neck— reconstructed in 1935
  • Sands Point Road Bridge in Sands Point— built in 1911
  • Bridge on Seawane Drive in Hewlett— built in 1932, reconstructed in 2002
  • Ellison Avenue Bridge in Westbury— built in 1941, reconstructed in 1960
  • Barstow Road Bridge over LIRR in Great Neck Plaza— built in 1935

  • Horseblock Road Bridge over Long Island Avenue and LIRR in Medford— built in 1940

While these bridges may not be imminently unsafe, they are in need of attention.  Currently some of these bridges are under construction, but not all.
