The off-ramp overpass that fell onto the southbound lanes of I-75 Monday night did not cause a lot of damage to the highway.
That doesn't surprise Andrew Hermann, past president of the American Society of Civil Engineers, who has been following the story. But he says the fact that the span did fall was surprising.
“Generally, they have demolition plans where they try to take into account all the possibilities as they’re taking down a bridge, to do it safely," Hermann said. "So it was very surprising to hear that it collapsed."
Update 1/20/15 2:51 p.m.: ODOT says the field investigation has concluded, and the clean up operations have started. In a press release, ODOT says debris removal is expected to take anywhere from 24 to 48 hours. After that, inspectors will look at the southbound lanes of I-75 to see if any repairs are needed.
Update 01/20/15, 12:45 p.m.: The Ohio Department of Transportation (ODOT) and the City of Cincinnati have released new information about Monday night's overpass collapse on southbound I-75.
