Project information

  • Location: Lawrence and Atlantic Beach, New York

  • Client: Nassau County Bridge Authority

  • Services: Fathometer Survey; Scour Evaluation

Boswell Engineering’s Marine/Waterfront Division performed a fathometer survey of the Atlantic Beach Bridge over the Reynolds Channel. The survey data was collected with an Electronic Range-Azimuth survey system in combination with a digital recording depth sounder. The limits of the survey extend 100-feet from each bridge fascia, covering an area of approximately 232,500 square feet. The purpose of the inspection was to determine the overall condition of the mudline and determine whether scour or aggradation was occurring. All findings were submitted to the client in a detailed fathometer survey report.
