Is wood supporting Celanese Road bridge over I-77 in Rock Hill? Here’s what SCDOT said
As you travel in Rock Hill on Celanese Road under the Interstate 77 bridge, you might see a strange — and perhaps alarming — sight.
Traveling west, you’ll see a large foam sheet supported by plywood under the bridge with three smaller vertical legs. It might give the impression they help support the bridge.
That’s not the case.
A reader took a photo and others have asked questions. Many wonder if it’s a part of the bridge’s structure.
It’s not.
The form board is being used to mold concrete during bridge deck repairs, according to the South Carolina Department of Transportation. SCDOT did work on the bridge over a month ago. More repairs came last month after a piece of concrete fell from the overpass.
The foam sheet and wood you see driving under the bridge are temporary, according to information in a SCDOT email.
“This is a temporary installation during the construction process and will be removed. This is a common construction technique for concrete work,” SCDOT said via email.
SCDOT traffic counts show a range of 14,000 to more than 47,000 vehicle trips per day. Celanese at that interchange shows 47,400 daily trips.
