The Sydney Harbour Tunnel has reopened southbound after being closed due to an overheight truck at the entrance to the tunnel.
The diversion via the Sydney Harbour Bridge has been lifted.
Traffic is still heavy back to Naremburn, so motorists travelling towards the city should continue to allow extra travel time and expect delays.
Traffic should slowly return to normal now that the tunnel is open again.
