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."
