Interstate 65 near Lowell, IN, was shut down Thursday, Nov. 16, because of a chemical leak at a nearby Pilot Truck Stop that injured several people.

According to WTHR-TV, a tanker truck that was parked in the lot apparently leaked sodium hydrosulfite, a chemical used in film, paper and leather products that can cause skin and eye irritation.

A sheriff's officer said five people were treated for respiratory problems. The highway was expected to reopen by 4 p.m. Thursday.
