Interstate 70 has reopened after a tanker spilled an unknown quantity of hydrochloric acid around 11:45 a.m., which prompted the voluntary evacuation of restaurants at the Smithton truck stop.
"People in the restaurants were not subjected to any danger," said Westmoreland County spokesman Dan Stevens, adding the restaurants were allowed to reopen after the spill was contained and initial air monitoring assessments were complete.
The interstate was reopened about 4:14 p.m.
A motorist called 911 after seeing the tanker leak, which prompted state police to pull over the tanker, Mr. Stevens said. The tanker pulled off I-70 onto Fitzhenry Road and continued to spill. Fitzhenry Road will remain closed under the I-70 overpass until the truck is offloaded, Mr. Stevens said.
"There was a valve that was not completely sealed that was leaking," Mr. Stevens said.
Westmoreland County hazmat and a number of local fire companies responded to aid in cleanup efforts and traffic control.mobilehome - breaking - Transportation
