UPPER DARBY TWP, PA — Motorists traveling through Upper Darby Township, Delaware County, should prepare for delays on Monday, October 19, when SEPTA closes a section of Bishop Avenue for milling and paving operations, according to the Pennsylvania Department of Transportation (PennDOT).
At a Glance
- Roads Affected: Bishop Avenue, between Edgerton Road and Secane Road
