Overview
- PennDOT crews began tearing away the bridge deck over I‑376 with around‑the‑clock 12‑hour shifts and on‑scene video showed debris falling during demolition.
- Officials say it will take about two days to place explosive charges into pre‑drilled holes and that an implosion will occur later this week with no exact date yet announced.
- Supports for a new prefabricated span are already in place to allow a roughly 102‑foot lateral slide that engineers expect to perform after demolition and site cleanup.
- The Parkway East is closed between the Squirrel Hill Tunnel and the Edgewood‑Swissvale exits through an accelerated 25‑day window that PennDOT says runs to Aug. 3, and detours have rerouted roughly 100,000 vehicles onto local streets causing major backups and neighborhood strain.
- While the roadway is closed crews are also paving the Squirrel Hill Tunnel, repairing interchange expansion dams, setting new streetlight foundations, and running first‑responder training with contractors working under schedule incentives and penalties.
