(WPXI) A part of the Pennsylvania Turnpike will close overnight this weekend for crews to remove a part of a former bridge in Westmoreland County. The Turnpike will be closed in both directions between Pittsburgh and Irwin Interchanges on Sunday, Sept. 29 between 12 a.m. and 6 a.m. During that time, crews will remove the superstructure of the former Harvison Road Bridge in Penn Township that is over the turnpike at milepost 61.68. Before the closure, the turnpike will be reduced to one lane in the area of the former bridge to allow for a crane to be safely set up.
