FREMONT, Ind. (WANE) — Interstate 69 was shut down in Steuben County and southern Michigan due to a hazmat spill at a Fremont truck stop Tuesday. The interstate has since reopened.

The Indiana Department of Transportation tweeted a traffic alert just after 10 a.m.

Steuben County EMA Director Randy Brown told WANE 15 a semi tanker leaked 6,000 gallons of liquid nitric acid at the Pilot Truck Stop in Fremont when a valve broke.

Brown said the chemical was running away from the gas station’s pumps and into a ditch along the highway.

The interstate’s northbound lanes were closed at the 354 mile marker northbound, and the southbound lanes were closed at the 3 mile marker in Branch County, Michigan. The interstate has reopened.

Old U.S. 27 was also closed at S.R. 120, and side roads nearby were also.

Crews apply lime to a chemical spill off Interstate 69 on Sept. 14, 2021.

Brown said the county was working with IDEM on a cleanup effort. Lime was applied to the liquid in the ditch, which has been dammed off, Brown said.

The gas station was closed during the cleanup effort but has since reopened.
