A link road option will be considered alongside other east-west improvements within the Ngauranga Triangle.

Re-evaluation complete

April 2019

In September we updated you on the re-evaluation of the Petone to Grenada Link Road (P2G) project to align it with the new priorities set out in the Government Policy Statement on Land Transport (GPS).

The re-evaluation is now complete. The re-evaluation found that the need for improved east-west connections generally aligns with the Government’s priorities, but that the Petone to Grenada link road in its previously proposed form may not proceed.

The re-evaluation report recommends that the Transport Agency further investigates how best to improve resilience, safety, and east-west transport choice.  This means taking a step back and ensuring other east-west options across the state highway network (the triangle formed by SH1, SH2 and SH58) are considered. The timing of this work will depend on funding availability and other nationwide funding priorities.

A package of short term resilience improvements to the existing highways was also recommended.

In endorsing the recommendations, the Transport Agency Board has noted that a link road is required, but funding will be considered at a later date. The re-evaluation recommended that construction of an east-west connection be considered for funding from 2028.

We are yet to determine timing for the short-term resilience improvements, or for investigation of the longer-term options. The timing of this work will depend on funding availability and other nationwide funding priorities

Short-term resilience improvements

The re-evaluation identified that the short-term priority should focus on improving the resilience of the existing network. This could include measures such as stabilising slopes that border state highways and improving drainage.

Short-term work could also consider whether to extend the existing ‘Managed Motorway’ (smart motorway) concept to include more of SH1 and SH2.

The timing of this work will depend on funding availability and other nationwide funding priorities.

Long-term resilience, safety and transport choice improvements

Depending on funding availability, in the long term, we will develop and select a package of east-west transport improvements that will seek to increase the resilience of Wellington’s transport network, increase safety for all users, and improve transport choice for east-west journeys (between the Hutt Valley and Porirua/northern Wellington). We will also be mindful how such a connection will support local urban and employment growth patterns.

We will be taking the whole of the Ngauranga Triangle (the triangle formed by SH1, SH2 and SH58) in to account when considering the best long-term option for east-west journeys. A link road option will be considered alongside other east-west improvements within the Ngauranga Triangle.

Whatever form the project takes, it will be required to support the goals of improving resilience, safety and transport choice and will also be required to provide value for money, and to minimise adverse impacts on the environment.

Feedback from the community, including potentially affected landowners, received during previous consultations on options for this area will be considered when work commences.
