Part of a highway in the Finger Lakes, NYC region was closed for five hours Thursday evening after a tanker truck crashed, spilling 45,000 pounds of slippery liquid chocolate that hardened.

State Police said there were no serious injuries in the crash shortly after 5 p.m. A road grader was used to scrape the northbound lanes of Interstate 390.

Truck driver Bert Nestlrode, 46, of Ephrata, Pa., swerved to avoid a deer, the truck rolled over and the tanker split, police said. He was treated at a hospital for cuts and bruises and no tickets were issued.

The syrup also covered a bridge and a car on another road below. The truck, from M&M Mars. Co. in Elizabethtown, Pa., carried liquid used to make milk chocolate.

“It smelled like a Hershey bar,” Groveland Fire Chief Lloyd Butler said. “There was a lot of chocolate, but no peanuts.”
