In November 2018, 3TC began making room for the new third track at Floral Park Viaduct in the village of Floral Park. Floral Park Viaduct is the westernmost point of the new third track – this is the location of the existing bottleneck and where the new third track will be installed to alleviate the bottleneck. A viaduct is a bridge comprised of small spans – in Floral Park, the viaduct allows the train to be elevated above the streets of Floral Park.
