Point Marion Bridge will be imploded on Monday, weather permitting.
The Pennsylvania Department of Transport (PennDOT) has scheduled the demolition of the old Point Marion Bridge for between 7 am and noon Monday. Explosives will be used to drop the 79-year-old closed bridge into the Monongahela River.
During the process, a mandatory 800-foot safety zone wii surround the demolition area, requiring the closure of the new bridge next to the old span and its pedestrian walkway and surrounding roadway.
