Sydney Harbour Tunnel closed: Traffic delays for peak-hour commuters due to overheight truck

Drivers can expect significant delays following the closure of the Sydney Harbor Tunnel, which was caused by an over-height truck triggering sensors.

The B-double has been reversed into a driveway, but the tunnel is still closed to southbound vehicles.

All southbound motorists will be diverted to the Harbor Bridge.

Traffic is moving bumper to bumper back to the Lane Cove Tunnel on the Gore Hill Freeway near Artarmon.
