The crash happened on I-81 South at mile marker 93 in Swatara Township shortly after 4 a.m. on Thursday, August 1, as detailed by Schreffler.
There was "heavy entrapment" and one of the tractor-trailers rolled over, Schreffler explained. One driver was taken to Hershey Medical Center. The extent of their injuries is unknown.
"One of the tractor-trailers was carrying peat moss and the trailer broke open and the peat moss is covering the roadway," Schreffler said.
The interstate has closed between Exit 100: PA 443 - Pine Grove and Exit 90: PA 72 - Lebanon, according to Schreffler and 511PA. But crews were able to clear the shoulder to release two miles of traffic that had been stuck behind the crash.
"The roadway will remain closed for likely the whole morning," Schreffler, but at 11:20 a.m. she reached out to announce the roadway had fully reopened.
