Every month, the Wellington Transport Alliance closes each of the SH1 Wellington City tunnels at night including the Terrace Tunnel, Mt Victoria Tunnel and Arras Tunnel. The closures are required so crews can perform routine maintenance to keep the tunnels safe and operational for all road users.
Aside from regular maintenance, there is also an annual Building Warrant of Fitness (BWOF) closure for Terrace (4 days) and Mt Victoria (4 days) in March each year.
Occasionally there may be additional closures planned as required and these will be updated on this web page as they are scheduled. When the tunnels are closed, vehicles will need to take alternative routes to travel through SH1.
Check the schedule below for more information on when each tunnel closure is happening. The tunnels are closed at night, usually between 9pm and 5.30am. This is to avoid heavily impacting traffic during the day.
