State Road 66 between Epworth Rd. and Grimm Rd. has re-opened, according to the Indiana State Police. They were closed for a couple hours Monday as crews cleaned up a chemical spill.
Four people were sent to the hospital after they were exposed to the bleach-like substance.
Indiana State Police Sergeant Todd Ringle says a trooper and three drivers went to St. Vincent as a precautionary measure.
"If that chemical had gotten onto someone’s skin, it could’ve burned, but again, we didn’t have anybody who was experiencing that," Ringle says.
The Indiana State Police were called around a quarter after nine Monday morning. Dispatchers were told that several vehicles were pulled over with a substance on their windshields that wouldn’t come off.
A trooper arrived around ten, determined the chemical was hazardous, and contacted the local fire department.
Three different fire departments responded to the scene, along with state police and the Warrick County Sheriff’s Office.
Police say the tanker was headed toward Rockville but haven't determined exactly where.
State police believe the leak was an accident and won’t lead to any charges.
