Plan ahead for delays on SH1 Porirua to Tawa due to paving works - update 5 November


Waka Kotahi NZ Transport Agency is advising motorists to plan ahead for significant delays between Porirua and Tawa on Saturday 6 and Saturday 13 November, as Transmission Gully crews finish laying 1000 tonnes of asphalt along a 900m stretch of road connecting the southern end of the new motorway with the existing State Highway 1.

UPDATE 2: Friday 5 November 2021 4.44pm:

The builder of Transmission Gully has now advised that these paving works will not take place this weekend. The work scheduled for this weekend will now take place on Friday 12 November and Saturday 13 November.

UPDATE 1: Friday 5 November 2021, 3pm:

Due to weather, this work has been postponed by one day. It will now take place overnight between 6pm Saturday 6 November and 10am Sunday 7 November. Motorists should plan ahead for delays early on Sunday morning and delay travel until after 10am if possible.

In order to complete such a large amount of road paving, the road layout will be changed and reduced down to one lane in each direction between the following times:

  • 6pm, Friday 5 November – 10am, Saturday 6 November
  • 6pm, Friday 12 November – 10am, Saturday 13 November

Congestion and delays are anticipated as traffic builds between 8am and 10am on each Saturday morning, so motorists are advised to consider travelling after 10am on these dates, take an alternative route if possible, or just make sure to allow extra time for their journey. 

Waka Kotahi is reminding people who do need to travel through the area during the lane closures to adhere to the posted speed limit, maintain a consistent speed to keep traffic flowing smoothly, and keep a safe following distance.

These works are weather-sensitive and may be postponed. Waka Kotahi will provide an update on our social media channels if there are any changes to the timings.

This paving work is one of many things left to do before the new Transmission Gully motorway can safely and legally open.

As well as finishing works, there are other critical requirements which also need to be met by the Transmission Gully contractor, Wellington Gateway Partnership, and the sub-contractor, CPB HEB Joint Venture, including safety and quality assurance work, and compliance with environmental consent conditions. 

A new opening date for Transmission Gully has not yet been agreed. Waka Kotahi will provide an update to the community as soon as we can.

Plan ahead for a safe, enjoyable journey. Keep up to date with:
