A single-semi accident on I-80/94 in Lake County congested rush-hour traffic early this morning, the Indiana State Police said.

According to police, at 6:49 a.m. trucker Pierre Jordan, 34, of Chicago, was westbound in the right lane when, at the Grant Street overpass, he left the roadway for unknown reasons and struck a guardrail on the right shoulder.

The impact caused the rig’s fuel tanks to rupture, a large amount of diesel fuel was spilled, and it took responders until 8:30 a.m. to complete cleanup and re-open all lanes of traffic.

Jordan was driving for Pace Air Freight of Indianapolis.

The ISP is reminding motorists to pay close attention when driving in construction zones. “Distracted driving has caused two semi truck crashes in less than 24 hours at this particular location and each crash resulted in long unnecessary delays for the traveling public,” the ISP said.
