Construction Progresses at 60-Year-Old South Tyson Avenue Bridge

Construction is progressing at the 60-year-old South Tyson Avenue Bridge in Floral Park. To address an existing Main Line bottleneck where four tracks merge into two, room is being created for a new third track. The new third track will be installed east of the bridge to accommodate a future increase in capacity on the Main Line. 3rd Track Constructors (3TC) has been preparing the site for the construction of new piers, which will support the new third track.

The South Tyson Avenue Bridge has been in service since 1958. The bridge will be replaced using the method successfully employed at LIRR’s Post Avenue Bridge in Westbury, which was completed with limited disruption to train and road traffic, over a single weekend in October 2017.
