Dauphin County District Attorney Fran Chardo confirmed Friday that an incident that has closed part of Interstate 83 northbound is a police-involved shooting.

Traffic is badly snarled in the area near the Harrisburg Mall as the investigation continues.

Details about the shooting were few, but it was clear that drivers should avoid the area near the Eisenhower Interchange for what likely will be several hours of investigation.

PennDOT reported significant traffic backups. Traffic was tied up back to the interchange with Interstate 283.

PennDOT spokeswoman Fritzi Schreffler said the recommended detour around the scene is to take Route 581 west to Interstate 81 north. “While 83 south is not closed, we highly recommend avoiding it because of rubber necking,” she said.
