Vanderbilt Cup Races

This past weekend's mystery photo was the remnants of the Oyster Bay LIRR Bridge/ Williston Park & East Williston bridge abutment. By the 1970's, it was becoming clear that the 2 remaining railroad bridges were a safety hazard and nuisance and needed to be demolished.

With these recently 1982 plans to the VanderbiltCupRaces.Com archives donated by Pat Babor, we can see exactly how the LIRR removed these bridges in 1983 with a very active RR track below.

Dated February 5, 1982 these newly uncovered plans include then-current site views, original 1909 bridge construction plans and new drawings for demolition, and crane placements

As we've seen from any other Motor Parkway bridge removal, these original parkway bridges were overbuilt to last for an indeterminate amount of time. To this day, 113 years later, there are two in Nassau (Old Courthouse Rd & Old Bethpage) that have stood the test of time with little to no maintenance for decades.

Back then, bridges such as these, or even much larger infrastructure projects like NYC's Brooklyn Bridge, built between 1869 to May 24th,1883, life spans were thought to be indefinite, unlike today, with maximum 50-year life spans figured into the planning.

The next drawings within the plans showed crane placement details. Here, for the 3 cranes needed for the East Williston bridge.

It's interesting to note that even the swing of the cranes were noted on the plans so as to not interfere with each other or their surroundings.

Difficult to see, but these drawings provide the crews with proper rigging for the cranes to hoist the beams from their original positions.

Demolition day arrives

In the early 1980s, Ron Ridolph photographed the Long Island Motor Parkway from Fresh Meadows to Lake Ronkonkoma. Among the events documented by Ron was the demolition of the bridge between Williston Park and East Williston in 1983.
