The aging Grand Avenue bridge over Interstate 670 will have to be replaced, the Missouri Department of Transportation announced Friday.
The bridge has been closed since May 6, when small pieces of concrete started falling off of it, District Engineer Dan Niec says.
It cannot be repaired.
“The current design of that bridge was modern for that time, for that era, when it was built back in the ’60s,” Niec says. “Those types of bridges are no longer built.”
