The Ohio Department of Transportation is asking people to do their part to prevent litter from accumulating along the state’s roadways.

On average, ODOT crews collect more than 400,000 bags of people’s trash from along Ohio highways and roads each year.

The effort costs Ohioans around $4 million annually.

ODOT says it’s disappointing that their workers have put so much time and effort into an issue that’s 100 percent preventable.

ODOT also points out that picking up trash takes them away from important jobs like filling potholes and fixing guardrails.
