Wellington Road Report
Extended closures planned – State Highway 1 Wellington tunnels
With extra maintenance work planned, Wellington drivers can expect additional closures of the Mount Victoria and Terrace tunnels this month and in June.
Terrace Tunnel:
Four sets of night closures are planned: 11 May (Monday); 26–28 May (Tuesday – Thursday); 8 June (Monday); and 22 – 23 June (Monday – Tuesday). Closures will be in place from 9 pm to 5 am.
Mount Victoria Tunnel:
Two sets of closures are planned. The first will be on Tuesday, Wednesday, and Thursday nights next week (12-14 May), followed by Tuesday, 9 June. The tunnel will be closed to all traffic between 9 pm and 5 am.
Contractors will carry out routine maintenance in the tunnel and also complete resurfacing works on Ruahine Street.
Traffic travelling between the Wellington CBD and Kilbirnie/Miramar will have to detour on local roads via Adelaide Road, Riddiford Street, and Constable Street (see map below). This will require extra travel time and drivers should plan accordingly.
During these closures, work crews will carry out routine tunnel maintenance, resurfacing work north of the tunnel, and tree trimming. This will also require a full closure of the northbound Clifton Terrace onramp.
Drivers will have to use alternative routes to leave the Wellington CBD – e.g., Aotea Quay, Molesworth Street, Murphy Street, Hawkestone Street.
Arras Tunnel:
There will only be one Arras Tunnel closure before the end of June. This is planned for Wednesday, 10 June.
There were previously five tunnel closures scheduled for May to June. A further eight closures have been added to complete essential road resurfacing and tree maintenance works.
