PennDot says the Perkiomenville Road Bridge, over the Goshenhoppen Creek in Upper Frederick Township, will have lane restrictions on Thursday and Friday, December 1 and 2, from 9:00am until 3:00pm. Workers will remove sediment from the creek and add rock to stabilize the abutments.  The one-span bridge, built in 1927, carries about 1,500 vehicles a day.
