M4 Tunnel Reopens After Emergency Closure Over Shotcrete Bulges

Officials plan investigations into communication failures, requiring safety assurances.

Overview

  • Transport for NSW said the tunnel fully reopened in both directions ahead of the Friday morning peak following overnight repairs to damaged sprayed-concrete lining.
  • Engineers identified two large bulges in the westbound roof during an overnight inspection, triggering a safety shutdown between Haberfield and North Strathfield.
  • Drivers reported being stuck in the tunnel and on approaches for up to three-and-a-half to four hours before one westbound lane reopened in the afternoon.
  • NSW Roads Minister Jenny Aitchison and Transport for NSW leaders criticised Transurban for weak communication and for initially declining government engineering support.
  • Transurban issued an apology, undertook remediation, and offered toll refunds through Linkt as the government moves to secure formal assurances on structural integrity.
