The Pennsylvania Turnpike Commission is jumping into accelerated bridge construction (ABC) with both feet, tackling replacement projects scheduled at opposite ends of the Keystone State over the next two weeks.
Over the weekend of Sept. 22-25, Brayman Construction Corp., Saxonburg, Pa., will demolish a 66-year-old, 150-ft-long concrete box-beam bridge that carries the turnpike, or I-76, over Brush Creek in Beaver County, northwest of Pittsburgh. A new steel-plate-girder structure, designed by SPK Engineering Inc., Uniontown, Pa., will take its place, providing a safer crossing for approximately 40,000 vehicles a day.
