Project information

  • Location: Orange County, New York
  • Client: New York State Thruway Authority

  • Disciplines: Construction Engineering, Inspection

The Woodbury plaza located within the Harriman Interchange (Interchange 16) on the New York State Thruway (NYST) system serves as the southern portal to the Thruway's gateway to the Catskills and to upstate New York and the Canadian border. The primary goal of the $79 Million Phase Two mainline and toll plaza reconstruction was to provide Highway Speed E-ZPass (65 mph) and improve safety of the NYST patrons through this heavily traded corridor. The specific project objectives were to: Reconfigure the toll barrier to accommodate four - Highway Speed E-ZPass Electronic Tolling lanes; relieve congestion; reduce queuing of traffic at the approaches on either side of the barrier; improve the level of mobility through the project area; and rehabilitate deteriorated mainline pavement in order to provide a smooth riding surface through the 3 - mile project limits (MP 43.5 - MP 46.4).

Boswell’s field design engineer, utilizing "Microstation" CAD software coupled with the skills and survey techniques of our Field/Resident Engineer made it possible to: accurately track quantities; create 3-D modeling and visualizations which enabled unanticipated or differing field conditions, to be adusted on an immediate basis. Boswell Engineering's expertise in perfecting this cutting - edge and innovative procedure, enabled this project to remain on schedule with minimal impact to the traveling public, mitigated contractor claims, and ultimately resulted in a substantial cost savings to the New York State Thruway Authority.
