KING OF PRUSSIA, Pa. (CBS) — Emergency construction crews continue to repair a giant sinkhole that is slowing down traffic at the Schuylkill’s King of Prussia interchange. It is located in the westbound lanes where the roadway splits — I-76 goes to the left and the lanes to the right are for Mall Boulevard, 202 and 422.

Only the far-right shoulder is able to get by westbound, between Route 202 and Mall Boulevard.

What was initially thought to be a quick fix has become more complicated due to the discovery of more moisture and water underground.
