HARRISBURG, Pa. (AP) — Pennsylvania is among the nation’s leaders in bridges that both lack backup protection against collapse in case a single, vital component fails and are designated by highway officials as being in need of repair.
Pennsylvania has 577 such bridges, according to a state Department of Transportation list.
Some are among the busiest in the state, including the 85-year-old Liberty Bridge spanning the Monongahela River in Pittsburgh and an Interstate 95 span in Philadelphia.
Scott Christie is PennDOT’s deputy secretary for highway administration. He says any bridge in Pennsylvania that is deemed unsafe by an inspector is closed. He says that the bridges on the list warrant more frequent inspections, but that being on the list doesn’t mean they’re unsafe.
