Bridges that carry Route 22 over Interstate 81 in Harrisburg, as well as the interstate in both directions beneath those bridges, remain closed more than 24 hours after a fiery tanker crash the occurred early Thursday morning.
The accident occurred on the ramp from northbound I-81 to westbound Route 22/322. I-81 in the vicinity of its Exit 67 interchange is expected to remain closed for several days.
"One bridge has been seriously damaged, is no longer safe, and the spans over both northbound and southbound I-81 will be demolished and removed," said a spokesman for the state Department of Transportation.
"Prep work started last evening and demolition should start today. This work is expected to take a few days to complete before it is safe to allow traffic underneath on I-81. The contractor hired for this assignment is working around-the-clock to remove the bridge to enable PennDOT to reopen I-81 as soon as possible."
The tanker truck overturned and caught fire on the ramp from northbound I-81 to westbound Route 22/322. The deck was destroyed and must be replaced. Plans are to remove the deck of the bridge span over I-81 during the next few days. It also may be necessary to remove the entire superstructure of the bridge, including the beams. Traffic will not be allowed on I-81 under that bridge is removed.
A detailed advisory on traffic impacts throughout the Harrisburg area was released Friday morning by PennDOT :
