I-75

The construction company in charge when the exit ramp collapsed onto I-75 last month says it made an engineering mistake that may have lead to the collapse.

Kokosing CEO Wm. Brian Burgett issued the following statement:

Construction continues on the I-75 / Hopple St. interchange continues overnight beginning Wednesday evening. Here are the details from the Ohio Department of Transportation.

Work at the I-75/Hopple interchange will require the following closures this week:

·         Various lane closures on Marshall Avenue and side streets from 9 a.m. to 3 p.m. each day.

·         Single left lane closure on southbound I-75 from 7 p.m. to midnight Wednesday, Jan. 28.

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."

The Ohio Department of Transportation says the field review of the Interstate 75 off-ramp collapse took less time than expected, meaning the clean-up and repairs were finished sooner than anticipated.  ODOT spokesman Brian Cunningham says the only damage to the four southbound lanes of I-75 was a two-foot by two-foot hole.

“Speculation was there were going to be multiple areas that would need to be fixed.  And that just wasn’t the case,” Cunningham says.  “And so when the assessment was done, it was evident that there was just one particular area that had damage to it.”
