The longest cable-stayed bridge in the United States is being evaluated for salt corrosion. The Arthur Ravenel Jr. Bridge in Charleston is being looked at by South Carolina transportation officials and bridge maintenance engineers to see if there is salt corrosion below the driving surface of the bridge.
The Post and Courier reports that some of the inch-wide pieces will be removed from the road bed so these engineers can look below the driving surface for corrosion caused by the saltwater from the Cooper River. They want to know if this water is causing damage to the bridge’s concrete base because the salt could cause the steel used to reinforce the slabs to rust. The bridge is only five years old and cost more than $630 million to construct.
