Summary

  • A controlled blast reduced Pittsburgh’s Commercial Street Bridge to rubble, clearing the way for a replacement span already built by PennDOT.
  • The new bridge will be slid into place at 19 feet per hour in what authorities call Pennsylvania’s largest lateral slide project.
  • The demolition followed a one-day postponement, with the bridge on I-376 torn down Thursday morning after the delay from Wednesday.
  • I-376 will remain closed until August 3 as crews prepare for the slide-in and complete the bridge replacement.
