Measuring a Bridge That Never Stops Moving

How do you create a centimeter-accurate survey of a heavily traveled lift bridge without closing a single lane or disrupting marine traffic? McKim & Creed’s Geospatial team combined mobile mapping, terrestrial lidar and survey control to capture the Cape Fear Memorial Bridge in Wilmington, N.C., while more than 65,000 vehicles continued to cross the bridge each day.

Geo Week News takes an in-depth look at the innovative approach led by National Geospatial Director Matt LaLuzerne, PSM, and supported by team leads Trevor Tyson and Martin Taylor. The article explores how the team overcame vibration, limited access and challenging control conditions to deliver a centimeter-accurate 3D survey for NCDOT, demonstrating how creative applications of geospatial technology can make complex infrastructure projects safer and more efficient.
