A chemical spill Tuesday morning shut down northbound and southbound lanes of Interstate 75 in northern Madison County, an emergency management official said.
Emergency officials were still dealing with the issues stemming from the spill Tuesday afternoon. Motorists were being diverted onto U.S. 25, which runs parallel to the interstate.
Southbound lanes on the interstate reopened about 3:40 p.m., and the northbound lanes reopened about 4:30.
The spill from a tanker truck had shut down the interstate to northbound traffic at exit 90 at Richmond and southbound traffic at exit 97, just south of the Kentucky River and the Clays Ferry Bridge, said Michael Bryant, deputy emergency management director for Madison County. The truck is in the northbound lanes between the Boonesboro Road exit and the U.S. 421 exit, he said.

The truck was leaking ferric chloride solution from one of its valves, Bryant said.
"It's my understanding that it does have a trail to it. How long that trail is, I don't know," Bryant said.
Ferric chloride solution is often used in potable water and wastewater treatment plants, food and dairy plants, and as a copper etchant in the electronics industry.
The spill happened about 10:45 a.m. Tuesday.
First-responders included Kentucky State Police, the Madison County Fire Department, the Blue Grass Army Depot Fire Department and the White Hall Volunteer Fire Department.
Bryant said the leak was stopped and the evacuation at the time of the spill was just a precaution. No one was injured.
