Long Island Expressway Noise Barriers

NYSDOT Region 10, NY


About this Project

Under an on-call services contract with New York State DOT Region 10, FST completed design for replacement of a noise wall along the LIE at Exit 37. Work included resolving the discrepancies in the as-builts and field conditions of the existing structure; inspection of previously installed concrete noise wall footings for possible reuse; design of new noise wall and footings, and new noise wall panels on top of previously installed footings. 

Other work included surveying and mapping, utility investigations, MPT, and lighting and Nassau County DPW sewer force main relocations.
