Starting Friday, PennDOT will begin a rehabilitation project on two bridges spanning Platt Hollow Road in Juniata County. The work includes superstructure replacement, paving, and drainage upgrades. Beginning next Tuesday, April 15th, there will be a 14-foot width restriction and single-lane traffic. The Thompsontown eastbound on-ramp will be closed, with a detour in place. The $4.3 million project is expected to be completed by September.
