The Wando Bridge on Interstate 526, a portion of which was shut down Monday for emergency repairs, was designed by the same engineering firm as a pedestrian bridge that collapsed and killed several people in March.
The Wando Bridge, formally known as the James Burrow Edwards Bridge, was designed by FIGG Bridge Group, and constructed in the late 1980s-early 1990s, according to FIGG's website.
FIGG also designed the pedestrian bridge at Florida International University that collapsed during construction March 15, 2018, resulting in six deaths.
No other FIGG-designed bridges have ever collapsed the way the one did at Florida International, the group says on its website.
"We have worked on more than 230 bridges throughout the United States and have designed nearly 35 miles of bridges in the (southeast) that have withstood multiple hurricanes," FIGG said in a statement released after the Florida International collapse.
The Wando Bridge was under construction during Hurricane Hugo. The bridge connects Mount Pleasant to Daniel Island.
S.C. Dept. of Transportation officials shut down the westbound lanes of the Wando Bridge Monday after discovering a broken cable within the bridge's support system.
Traffic westbound was shut down at 2 p.m. Monday. DOT says the westbound lanes will remain closed up to 48 hours for assessments of the damage and repair plans to be made. Eastbound lanes are unaffected.
Westbound traffic on I-526 leaving Mount Pleasant is being detoured off I-526 at Long Point Road.
