MT. PLEASANT, SC (WCSC) - When it comes to the Wando Bridge, the South Carolina Department of Transportation hopes to hear something before they see something if another cable were to snap again.
SCDOT officials say acoustical monitoring and instrumentation will be added to the inside of the bridge which would allow for inspectors to hear a cable snap, according to a presentation at the SCDOT commissioners meeting Thursday.
Crews are currently working to add redundancy to the bridge which includes two additional main cables inside the bridge.
The presentation also went over a 2011 investigation of the bridge which gave five priority recommendations. Those recommendations included repairing cable locations, sealing more than 2,000 grout tubes, document all areas of water intrusion, further investigate the tendons in the bridge piers and analyze the load rating of the bridge.
SCDOT claims these repairs were made in 2014, then weekly inspections started in 2016 when a cable damaged by corrosion was discovered.
Issues with the bridge dated back to at least 2010, when duct tape was discovered to be used in multiple places.
Inspectors will also take a "robust approach" to inspecting the bridge and say they expect many more years of service from it.?
