CLAY COUNTY, Ind. (WTWO/WAWV) – A crash involving two semi-trucks slowed traffic in the westbound lanes of I-70.

The crash happened on Monday just before 9 p.m. near the 23 mile marker in Clay County.

According to Sgt. Matt Ames with Indiana State Police, traffic was backed up due to construction when the driver of a semi failed to observe the slowed traffic and rear-ended another semi before running off the interstate and into the center median.

Sgt. Ames said one person was transported an an area hospital with non-life-threatening injuries.

As traffic was starting to clear from that incident, crews were called out to a vehicle fire near the 21 mile marker. That caused more traffic delays as firefighters worked to put out the blaze. No other details have been made available.
