The modification of South Tyson Avenue Bridge, which has been in service since 1958, is expected to begin Fall 2018. The bridge will be modified to include a new two-track bay bridge. South Tyson Avenue Bridge will be replaced using the method successfully employed at LIRR’s Post Avenue Bridge in Westbury, which was completed over a single weekend in October 2017. The modification of South Tyson Avenue Bridge is part of a broader LIRR initiative to support the growth and development of Long Island.
