DAYTON, Ohio (AP) — State transportation officials who studied last month's flooding of southwest Ohio highways say no major changes are needed.
The Ohio Department of Transportation says the flooding that overwhelmed sections of Interstate 70 and Interstate 75 north of Dayton was the result of unusually heavy rain. The agency says so much rain fell in some locations that it was the equivalent of a 1,000-year flood.
The agency said in a report released Thursday that the highway wasn't designed for the "rare and extreme" event that resulted in 4 feet of water on some sections of the highways and required motorists to be rescued from their swamped cars.
The Dayton Daily News (http://bit.ly/1pRskRr ) reports that total rainfall in the area of the flooding was about 4 ½ inches in a two-hour period.
