The crash, on Route 581 in Cumberland County, caused multiple injuries but none that were considered to be life-threatening, the Pennsylvania State Police said in a tweet.

The crash was reported shortly after 2 p.m. EST, according to the Patriot-News of Harrisburg, which cited a report from 511PA.

The pileup blocked all three lanes of the highway, WHTM-TV reported. Troopers are directing motorists to take alternate routes, according to the television station.

Traffic maps showed that drivers slowing to look at wrecks are delaying traffic, the Patriot-News reported.

It is not known when the highway will reopen, the state police said.
