Road works and closures

Before you drive, check the most up-to-date road closure information so you can plan an alternative route.

Tunnel safety

  • 5.1m eastbound
  • 5.1m westbound

Driving tips

  • Do not enter the tunnels if you are driving an over-height vehicle.
  • Ensure your load is secured so it doesn't trigger over height detectors (this may result in a road closure while we investigate the cause of the trigger).
  • Observe roadside signs for the alternative route provided.
  • We recommend that customers close their windows and turn on recirculated air when driving through tunnels.
