I-75, I-70 flyover ramp crashes: How often do they happen?

I-75 North to I-70 West Ramp Crashes:

In 2019, the state has investigated three crashes on the ramp, including a crash involving a rolled semi that closed the ramp for several hours Wednesday into Thursday.

In January, a semi driver hauling approximately 2,400 feeder pigs lost control and overturned his semi.  Two to three dozen pigs were killed in the crash.

In March, a semi overturned on the ramp closing it for several hours while crews cleaned up the damage.  The driver in that crash was not hurt.

Following the crashes earlier this year, the Ohio Department of Transportation had placed an electronic billboard warning drivers to slow down on the ramp.
