The Pennsylvania Dept. of Transportation announced Friday afternoon that Pittsburgh’s fire-damaged Liberty Bridge will remain closed indefinitely as crews continue to repair 30 feet of a compression chord on a deck truss that was damaged in a Sept. 2 blaze. PennDOT, which hoped to finish the work by Monday, did not specify when the work would be done.
A prolonged short circuit in the third-rail power system of Washington, D.C.’s Metrorail system has been determined to be the probable cause for a January 2015 electrical arcing and smoke incident that killed one passenger and injured dozens more, according to the National Transportation Safety Board (NTSB).
