Interstate 65 south remains closed near Seymour due to a fiery crash. It was not immediately clear how long the closure would last. Because of the chemical fire, ISP and responders chose to let the fire burn out instead of putting water on it. Wheeles said crews were concerned that adding water could cause a reaction that could make the situation worse.
The crash happened at mile marker 43 when two trucks that were stopped for a previous crash were rear-ended by a third truck. Southbound remained closed until about 9 p.m. The truck carrying the chemicals caught fire after the crash, prompting the evacuations.
Police are still investigating the crash.
Police said three semi trucks were involved in the crash, one of which was previously believed to be a leaking tanker, but turned out to be a box trailer. ISP said they have yet to determine what if any charges will be brought against the driver that caused the crash Wednesday.

Wheeles said a passenger in the sleeper compartment of one of the tractor trailers was injured but is expected to recover.
Police said that it will take hours to clean up the situation.
