Delaware State Police are investigating a crash in Wilmington Saturday afternoon when a pickup truck went down an embankment.

About 1:40 p.m., a 79-year-old Wilmington man was driving a 2015 Ford F150 pickup south on Carr Road from Marsh Road, said State Police Master Cpl. Gary Fournier.

For an unknown reason, the driver went off the road and the front right bumper of his truck hit a guardrail. Then the truck veered left, crossing over a concrete median, across the northbound lanes, and through the guardrail. The truck came to a stop nose down above Shellpot Creek, Fournier said.

The driver was rescued from his vehicle after 25 minutes, according to New Castle County paramedics.

The man suffered head injuries and was transported to Christiana Hospital.

The road was closed for three-and-a-half hours while the crash was investigated and cleared.

Fournier said no charges have been filed, but the investigation is continuing.
