New Substation Transformer Heads to Its New Hillburn Home

O&R at mid-morning today hauled a nearly half a million pound new, giant, electric substation transformer through the heart of Rockland down Route 59 from West Nyack to the transformer’s new home in Hillburn.

The big move came off without a hitch about 10 a.m. today when the transformer was rolled out of O&R’s Operations Center in West Nyack to NY State Route 59 West. From there, the truck convoyed with a New York State Police escort on Route 59 West through Nanuet, Spring Valley, Monsey, Tallman, Airmont and into Suffern before crossing the Fourth Ave. bridge and arriving at the O&R substation there.


O&R’s contractor WJ Casey successfully completed the move using a specially-designed, 19-axle, heavy-duty, hydraulic, flat-bed trailer truck.


The trailer, transformer and its pusher truck are considered one unit. That unit is 239 feet long, 12 feet 4 inches wide, and 14 feet, 5 inches high. Its gross weight, including the pusher truck, which was on hand as a precaution, is 469,500 pounds.
