Interstate 81 is closed in both directions at the 22/322 overpass near Harrisburg, and many other roadways around the city are congested due to a massive fire involving a diesel tanker.
Route 22/322 eastbound is also closed at the interchange.
Westbound 22/322 was closed until about 10:30 a.m., when PennDOT reopened the highway over I-81 at the Exit 67 interchange.
Access is now also
available to northbound I-81 from westbound Route 22 at the interchange.
State police Trooper Robert Hicks said the crash occurred at 6:10 a.m. when the tanker, fully loaded with diesel, overturned on the I-81 northbound ramp to 322 West near mile marker 67.
The truck then caught fire and multiple explosions occurred.
The driver, a 52-year-old man from Dover, was able to escape the truck with minor burns. He was taken to Harrisburg Hospital, Hicks said. His name was not immediately released.
The truck was coming from Carlisle, and no other vehicles or people were involved. The crash is still under investigation.
The tanker was on fire for about 45 minutes on the 22/322 overpass.
PennDOT officials said both roads will remain closed until further notice because they are worried about the structural integrity of the overpass.
PennDOT spokeswoman Fritzi Schreffler said it appears the decking and beams of the overpass are in bad shape, and it is simply too dangerous to let cars travel underneath on I-81.
I-81 north is closed at Route 581 in Cumberland County. I-81 south is closed at the 81/83 split.
Significant traffic delays have been reported on I-81, Route 22/322, Progress Avenue, Cameron Street, Linglestown Road, Route 581, Route 11/15, and the Carlisle Pike.
