MILTON -- If you're traveling west of here and planning to use Interstate 80 this afternoon, you'll want to find a new route. The highway is closed in both directions across a 34-mile stretch between Milton and Lock Haven due to a crash involving several vehicles in Clinton County, PennDOT says. The state is detouring westbound traffic onto Interstate 180 and Route 220, and eastbound traffic onto Route 220 to Interstate 180.
