King of Prussia PA – Periodic lane closures are scheduled on Interstate 95 and Route 309 in Delaware and Montgomery counties on Monday, March 21, through Friday, March 25, from 10:00 PM to 5:00 AM the following morning, for large sign maintenance, the Pennsylvania Department of Transportation (PennDOT) announced today.
