Marc Basnight Bridge will be closed to traffic for 30 minutes Tuesday morning while the state Department of Transportation is performing a high-resolution scan.
The closure will take place from 10:30-11:00 a.m. Tuesday on the bridge that carries N.C. 12 across the Oregon Inlet on the Outer Banks.
Flaggers and message boards will be in place on both approaches to the bridge to warn motorists of the closure, the department said in a release.
A device will be mounted during the scan on a slow-moving vehicle that will map the elevation and coordinates for millions of points along the bridge deck. The equipment is sensitive and needs to perform the scan without interference from passing traffic.
The Basnight Bridge was built to last 100 years and is designed to expand and contract with changing weather conditions. The 3-D scan survey will provide engineers with data they need to ensure the long-term health of the bridge, officials said.
