Motorway closures and detours

3 November 2015

If you regularly travel in or out of Wellington City, or are planning to soon, be aware there are four more overnight closures of the motorway coming up in November.

This is a photo showing new overhead gantries being installed on the Wellington motorway by crane at night. The work is part of the project to turn this section of highway into a smart motorway.

The motorway is expected to be closed in both directions between Ngauranga and Thorndon for up to nine hours at a time on the following dates:


  • 10pm on Saturday 14 November to 7am on Sunday 15 November
  • 10pm on Sunday 15 November to 5.30am on Monday 16 November
  • 10pm on Saturday 28 November to 7am on Sunday 29 November
  • 10pm on Sunday 29 November to 5.30am on Monday 29 November

Note – these dates could change due to bad weather or other unforeseen circumstances.

The closures by the New Zealand Transport Agency are part of the Smart Motorway project and are required to install four new cross-motorway steel gantries (the structures that house the destination or electronic signs) and carry out other related work.

You’ll still be able to get into and out of Wellington at all times, but you’ll need to factor in extra time to get where you are going and follow the detours. Watch for details on the electronic message boards on the highway and the extra mobile signs that will be in key spots around town.

Heading north

Northbound traffic will be diverted from the motorway onto the Tinakori off-ramp. The detour will take traffic along Tinakori Road, the Hutt Road and re-connect to either State Highway 1 or State Highway 2 at Ngauranga.

Heading south

South and westbound traffic travelling into Wellington City on State Highway 1 or State Highway 2 will be diverted at Ngauranga and travel along the Hutt Road, entering the city at various points or re-joining the motorway at the Hawkestone Street on-ramp.

Use alternative routes

Drivers travelling north from the airport and Cobham Drive area are advised to use an alternate route eg the waterfront roads, and then the Hutt Road.

Drivers at the Basin Reserve and in Willis Street will also be encouraged to use the waterfront route and avoid The Terrace Tunnel.
