Sydney Harbor Tunnel closed: Traffic delays for rush hour commuters due to overweight truck

Drivers should expect significant delays following the closure of the Sydney Harbor Tunnel, caused by an over-height truck that triggered sensors.

The B double has been backed into an access lane, but the tunnel is still closed to southbound vehicles.

All southbound drivers are being detoured to the Harbor Bridge.

Traffic is heavy returning to the Lane Cove Tunnel on the Gore Hill Highway near Artarmon.
