PennDOT says it could be Saturday afternoon until the roadway fully reopens again.
It all began around 5:00 a.m. when a 70-foot-long section of concrete pavement on the north side of the intersection with Mall Blvd. dropped about four to six inches.
The northbound lanes of Route 202 remains closed from Mall Boulevard to Allendale Road.
Then, on Friday afternoon, PennDOT discovered the sinkhole extended into the southbound lanes and closed those as well.
PennDOT advises Route 202 motorists to follow the posted detour of South Gulph Road, Church Road and Henderson Road to travel around the road closure.
The situation under Route 202 also includes a broken sewer pipe and water pipe, PennDOT said. Both utility pipes are in the process of being repaired.
The area has a history of sinkholes due, in no small part, to the limestone formation under the ground.
The average daily traffic volume on northbound Route 202 in the area of the Mall Boulevard intersection is 45,000 vehicles a day.
