Tanker truck on I-81 in Maryland flips, spills ammonium nitrate, prompting evacuations

A tanker truck carrying ammonium nitrate overturned on I-81 in Maryland, causing a temporary shutdown of the roadway and the evacuation of nearby businesses. The incident occurred early Monday morning near Halfway Boulevard in Hagerstown, Maryland, as reported by State Police.

Initial findings suggest that a blown tire led to the truck veering off the road, crashing through a guardrail, and ultimately rolling over into an embankment. Approximately three gallons of ammonium nitrate spilled onto the road, prompting authorities to evacuate businesses within a 1,500-foot radius as a precautionary measure.

The driver of the truck, a 32-year-old man from Pennsylvania, was taken to Meritus Medical Center for medical attention. His current condition remains unknown, according to Fox 5 DC.

Evacuated individuals were allowed to return to their businesses by 9:30 a.m., while the northbound lanes of the interstate reopened by 8:50 a.m. However, the southbound lanes remained partially closed as officials continued to investigate the cause of the crash.

The incident serves as a reminder of the potential dangers associated with transporting hazardous materials on highways. It underscores the importance of stringent safety measures and protocols to prevent such accidents from occurring in the future.
