Boswell Underwater Engineering (BUE) conducted an underwater diving condition survey inspection and fathometer survey of the new Goethals dual – span cable – stayed twin bridge. The fathometer survey data was collected with an Electronic Range-Azimuth survey system in combination with a digital recording depth sounder. The limits of the survey extended 100-feet from each bridge fascia, covering an overall area of approximately 215,500 square feet. The inspection surveys took place shortly after the opening of the new Goethals Bridge which will now serve as the baseline for comparisons with future surveys.
