10/5/2019 3rd Track Constructors


Siefert Associates aided in the demolition and erection of the new Nassau Blvd railroad bridge in Garden City, NY as part of the third track expansion on the LIRR. Engineering lift plans for precast abutment segments and temporary false work designs for the staging of the existing bridge were successfully completed.
