Overview
- Two of the four century-old tubes are being rebuilt after Superstorm Sandy damage and decades of deterioration.
- Officials report six months of progress in a 13‑month outage for Tube 2, which closed in May and is targeted to reopen in July 2026.
- Crews have removed damaged bench walls and conduits and begun structural rebuilding while working around the clock.
- Following the rebuild, new signal and electrical systems will be installed, then tested, with a planned three‑month transition before a roughly 13‑month Tube 1 phase starting in fall 2026.
- With only three tubes available, tunnel capacity is about 75% as agencies coordinate LIRR and NJ Transit operations, and the two‑tube rehabilitation is projected to finish in 2027.
