A portion of northbound Route 222 was closed for several hours after a milk tanker crashed early Tuesday in Ephrata Township.
The accident occurred north of the Ephrata/Route 322 interchange.
Officers responded to the area around 12:30 a.m. and found that the truck had traveled off the right side of the road, down an embankment and into a wooded area where it overturned, according to Ephrata police.
The driver, 32-year-old Zachary Schwabenbauer, of Nescopeck, told police he fell asleep prior to the crash, authorities said. He wasn't injured.
No other vehicles were involved in the accident.
The right northbound lane of the highway was closed for 2 1/2 hours as crews from Ephrata Pioneer Fire Company and Haz-Mat worked at the scene to clean milk and diesel spillage.
The lane was then closed for about six hours during the day Tuesday while the truck was recovered. The closure extended about a tenth of a mile, according to Ephrata police Lt. Chris McKim.
McKim said he heard an estimate that the tanker was carrying 20,000 pounds of milk.
