A truck carrying butter burst into flames after slamming into an overpass on the Merritt Parkway Tuesday near the Connecticut/Westchester border.

Police say the truck was traveling northbound on the parkway at around 11:20 a.m. when it hit the King Street Bridge. The truck hit the bridge in New York, but came to a rest in Connecticut.

Firefighters from Greenwich and Rye Brook, New York were able to control the fuel spill fire in a matter of 15 to 20 minutes. "We had fuel oil burning on the roadway, the truck itself, and a lot of the butter due to its combustibility," says Greenwich Deputy Fire Chief Thomas Zack.

Still, with butter and debris cluttering the road, police had to shut down the northbound lanes for hours.

The 18-wheeler entered the parkway from I-287 and was traveling into Massachusetts. The driver and a passenger were uninjured. The driver said he was following GPS instructions from his phone.

Police say the driver of the truck will be cited.
