Multibeam Survey of Fortescue Road Bridge over Fortescue Creek
Downe Townsip, Cumberland County, NJ
In 2017, W.J. Castle, P.E. & Associates, P.C. completed the multibeam survey of the Fortescue Road Bridge over Fortescue Creek. The bridge is approximately 100 linear feet long and 40 feet wide and the survey extended approximately 450 feet upstream and downstream of the bridge. A contour plan and cross sections were developed from field date and a complete report was submitted to the client. All elevations were referenced to a known datum on the bridge and were in NAVD 88. The purpose of the survey was to document the channel bottom conditions as part of the investigation of the scouring activity located at and near the bridge structure.
