A major hazmat incident took place on Tuesday morning at a Pilot truck stop near the Michigan-Indiana border.

The Pilot truck stop at  6900 Old U.S. 27 in Fremont, Indiana, was evacuated around 7 a.m. on Tuesday due to a reported nitric acid leak from a semi truck.

Around 6000 gallons of liquid nitric acid reportedly leaked from the tanker due to a valve break, according to local news outlet WANE.

Locals were told to shelter in place and other nearby businesses were also evacuated.

A six-mile stretch of I-69 was closed for the spill, triggering major traffic backups in the area.

The incident remains under investigation.
