LIRR Post Avenue Bridge Replacement
In October 21-22, 2017, the LIRR replaced the Post Avenue Bridge in Westbury – a span struck by dozens of overheight trucks in recent years resulting in train delays. Work was completed ahead of schedule, with the first regularly scheduled train passing over the new bridge at approximately 1:48 a.m.

The new bridge’s height clearance now allows trucks of up to 14 feet to safely pass underneath, improving LIRR system infrastructure and service reliability. The old bridge -- that hovered over Post Avenue at 11 feet 10 inches -- had been struck by trucks between five and nine times per year in each of the past six years. Train delays in both in both directions would loom as LIRR crews worked to determine its safety and structural stability before restoring train service.
