They were doing demolition on the overpass when it collapsed:
CINCINNATI — An old bridge on Interstate 75 was undergoing demolition late Monday when it collapsed, killing a construction worker and shutting down a stretch of the interstate for what could be days.
The “catastrophic pancake collapse” happened about 10:30 p.m. as a crew prepared for demolition of the old Hopple Street overpass, according to a statement from the City of Cincinnati.
It was part of the old northbound off-ramp to Hopple Street. The new bridge is already open.
As the old bridge collapsed to the ground, a semi-tractor trailer driver crashed into the rubble, police said.
