Indiana State Police at the Lowell Post say a truck crash and the chemical spill that followed shut down I-65 in Jasper County for 14 hours. Monday night at approximately 9:39 p.m. (CST), officers from the Indiana State Police responded to a single vehicle crash on I-65 near the 227 mile marker, three miles south of the Roselawn exit, in which nitric acid was spilled onto the interstate. Troopers say a preliminary investigation revealed that the semi-tractor pulling a tanker trailer containing nitric acid was southbound on I-65 near the 227 mile marker when the driver went off the interstate and into the median, and the semi-tractor jackknifed and came to rest on the drivers’ side. Nitric acid was lost from the trailer. Both the driver and an Indiana State Police trooper went to a Crown Point hospital to be checked for exposure to nitric acid fumes. They were both treated and released. The interstate was closed for approximately 14 hours while hazardous materials teams from various fire departments and the Indiana Department of Environmental Management cleaned up the spill, and helped upright the tanker trailer. Indiana State Police say this is an ongoing investigation, but at this time neither the use of alcohol nor narcotics is suspected as having contributed to this crash.
