INDIANAPOLIS, Ind. – Explosions rocked part of I-70, causing a major interstate shutdown on Indy’s near east side Wednesday morning.

The semi-truck fire began shortly before 2 a.m. on EB I-70 at mile marker 85.1.

Two people were in the semi when they heard a pop and several explosions. That’s when they noticed intense flames.

Thankfully, both people were able to get out safely. The driver even had time to unhook his cab from the rest of the trailer.

But the flames proved to be a challenge for fire crews. There are no hydrants on the interstate, so they had to bring engines in for water. It took fire crews more than an hour to extinguish them.

They used over 200 gallons of water.

All lanes were shut down for about two hours, but the interstate is back open now.

Investigators are working to determine what caused the fire.
