The Terrace tunnel in Wellington has reopened in both directions after police moved an oversized truck this morning.
But the New Zealand Transport Agency has warned of delays as the backlog clears.
The tunnel was closed for about 25 minutes because the truck could not pass through and had to be turned around.
UPDATE: The crash has now CLEARED and all lanes are FULLY OPEN. Expect delays as congestion eases. ^MF https://t.co/RpUaQQTnTQ— NZTA Wellington (@NZTAWgtn) May 16, 2017
