The crash involved three semi trucks on I-65 southbound near mile marker 43 and eventually resulted in the closure of both southbound and northbound lanes.
Sgt. Stephen Wheeles noted that the fire situation on I-65 is continuing to deteriorate, saying that portions of the highway have been closed down.
Sgt. Wheeles with Indiana State Police said it appears that multiple hazardous chemicals being transported by one of the semis in the crash had a reaction when mixed together, causing the fire. Houses within a half-mile have been evacuated, according to his Twitter feed.
One of the semis was hauling hazardous material, which led to the chemical fire. Wheeles said the cleanup crews are dealing with an explosion risk. Southbound remained closed until about 9 p.m.
According to Indiana State Police, the interstate was closed due to power lines being down at Chase Street in northwest Indiana.
UPDATE: An I-65 crash that happened early Wednesday morning is now causing problems for responders. Around 11:30 a.m., state police said the northbound lanes were also being closed at exit 41. The collision caused a hazardous chemical to spill on the road. Crews will begin milling to the pavement Wednesday evening, beginning repairs that will allow Interstate 65 southbound to reopen.
Only one passenger in one of the semi trucks suffered minor injuries in the wreck.
