PUTNAM COUNTY, Ind. (WTWO/WAWV) — Update: According to Indiana State Police Sgt. Matt Ames, all lanes are now open on Interstate 70 after a mechanical issue caused a semi-truck hauling several cars to catch fire and lanes to be closed.

A mechanical issue reportedly caused a semi-truck pulling a car hauler to catch fire along Interstate 70 Wednesday morning.

The fire caused traffic to be shut down in the westbound lanes of I-70, with traffic diverted off the interstate at exit 41. The incident occurred near mile marker 32 of I-70 westbound.

Indiana State Police Sgt. Matt Ames said that after the driver pulled over into the emergency lane, the semi became fully engulfed with the cars on the trailer also catching fire.
