Overview
- The full 25-day closure of I-376 between the Squirrel Hill Tunnel and Edgewood‑Swissvale begins at 9 p.m. Friday to allow crews to lateral‑slide a prefabricated span into place.
- PennDOT used accelerated bridge construction with most work done off site and has attached monetary incentives and penalties to the 25‑day schedule to encourage on‑time completion.
- Recommended detours are published and a specialized 511PA travel‑time tool is live, and a staffed incident command center will monitor detour routes and adjust traffic signals in real time.
- Pittsburgh Regional Transit paused its university‑line construction in Oakland to ease local congestion while UPMC will continue Presbyterian Tower construction, and drivers report early backups on Route 28 and Highland Park approaches.
- Officials say the short shutdown reduces years of rolling lane closures but warn that debris cleanup and final site restoration could take weeks or months and that neighbors remain concerned about emergency‑response routing and overnight noise.
