Judith Collins promises to build link road between Petone and Grenada

News from NZ National Party
A National Government would build the Petone to Grenada Link Road, including the Cross Valley Link, National Party Leader Judith Collins confirmed in Grenada today.

“Building the Petone to Grenada Link should be a key priority for the region. But the Labour Government has failed to prioritise transport.

“What we’ve seen instead is commuters in this region slapped with fuel tax after fuel tax, a muddled Let’s Get Wellington Moving announcement and state highway funding cuts that saw the plans for Petone to Grenada effectively cancelled.

“For too long Wellington has been trapped in a cycle of talking but not delivering on transport. The region is choked by congestion. This needs to change. A National Government would get on with the job and deliver the Petone to Grenada Link Road.

“The Petone to Grenada Link Road would significantly add to regional roading resilience in Wellington, while unlocking productivity and commercial opportunities for the Hutt Valley. It would ease congestion for residents of Ōhāriu and the Hutt traveling to and from Wellington.

“It is expected to make peak morning journeys between the Hutt Valley and northern Wellington about 10 minutes faster and 7 kilometres shorter,” Ms Collins says.

“It will provide another route to and from the Hutt Valley when SH2 is blocked or Wellington city when SH1 is blocked. It will also open up future residential or business growth opportunities by making Porirua, Wellington and the Hutt Valley better connected,” says National MP Chris Bishop.

“This is a vital project to unlock the economic potential of Wellington. It will provide a route between Seaview and Tawa and will include the Cross Valley Link. It will provide a link to Transmission Gully and reduce pressure on the highway system from the North.

“It will create more resilience in the region and keep the Hutt Valley and Northern Wellington suburbs better connected in an earthquake, slip or crash. Commuters will see significant travel time reductions and it will create hundreds of new jobs and support growth across the region.

“Under a National Government, Wellington won’t be forgotten, instead Wellingtonians will see record investment including a second Mt Vic tunnel and electrification of the line to Ōtaki.

“National will deliver a plan that invests in this region. We will build new transport projects to get this city moving and unlock the development potential for all of Wellington,” Mr Bishop says.

    About time……..sooner the better

    Dear Judith Collins
    There are seven compelling reasons for NOT building the proposed Petone – Grenada Motorway:
    1. Parliament’s ratification of the COP21 Paris Accord which commits NZ to cutting greenhouse gas emissions;
    2. Parliament’s passage of the Zero Carbon Act 2019;
    3. More road capacity encourages more use of motor vehicles and produces increased greenhouse-gas emissions;
    4. Roadwork excavations would produce millions of cubic metres of soil and rocks for dumping somewhere;
    5. Roadwork excavations would produce vast volumes of greehouse gases from machinery and trucks;
    6. Roadworks would destroy that spectacular part of the Ngauranga Escarpment;
    7. The multi-million dollars the project would cost would be better spent on pressing needs in our community.

    Both Mr Bishop and B Smith need to get real. Petone to Grenada was cancelled not because of any political ideology, but because it simply did not stack up in terms of value for money. As it was, it would involve horrendous amounts of earth-moving, and therefore money for diesel earth-moving equipment, and cater fro relatively few people. Trucks can at present and in the future just use the Ngauranga Gorge and drive back up the Hutt Motorway to get to Petone. Same as it ever was. As Chris Horne says, the money is best spent on more pressing things, rather than a wasteful, illogical, road for few.

    The Cross Valley Link and the damage that would do by creating a road barrier between Petone and the rest of Lower Hutt continues to be mentioned in these items. No one has been able to explain to me how the Dowse Interchange or SH1 would cope with the influx of additional traffic from this build.

    Why are the public transport solutions always an afterthought? Chris Bishop included the extension of the Melling Line to Belmont/Kelson – but there’s no timeframe mentioned and it’s after all of this road building exercise. Perhaps we can get traffic moving more freely by extending public transport to get cars off the road. The Gracefield Branch could be used to provide park & ride services for Eastbourne, or even extended to Wainuiomata (an extension which might start to meet BCR requirements with the planned growth to that suburb).

    The advocation for extending electrification to Otaki is positive though. I thought that a great COVID infrastructure initiative would have been to fill in the gap between Waikanae and Palmerston North – but no, roads were again the preferred infrastructure ‘solution’.

    @ Andy Mellon – A big YES to extending the Gracefield Branch via a tunnel to Wainuiomata, as per plans suggested by the Wainuomata Borough Council in 1975. The suburb housed 20,000 residents back then, but population declined over subsequent decades, in no small part due to the lack of decent public transport connections to anywhere else. The rail plans fell victim to the cars-only mentality that pervaded transport-policy at the time, and the sole transport link remains the road which crests at nearly 200m above the Hutt Valley at a gradient of 1 in 10. The tunnel, begun in the 1930s, remains incomplete and unsuitable for modern needs.

    Now the suburb’s fortunes are on the rise along with its house prices. A push is being made to lift its former declining image, and connection to the regional rail system would be just the ticket. It would also benefit the Hutt Valley by reducing vehicle-traffic from Wainui. Better value than the proposed Petone-Grenada motorway and Cross-Valley link? Quite probably!

    Any rail link to Wainuiomata would require a totally new tunnel, as the existing partial tunnel is too steep. However new tunnels at North/South Junction would probably be a higher priority (allowing full double tracking and higher frequencies on the Kapiti line).

    @ Greenwelly, Indeed, double-tracking of North-South Junction should be high on the list, but this is a project of ‘National Significance’ in that it would benefit more than just the metro trains.
    By contrast, any improvements to Wainuiomata’s access would be a purely local project and presumably would come out of a different budget. That’s why I rate it against the P2G m’way and cross-valley link, as these are essentially local projects also (given that State Highway 58 already exists for non-local traffic to get from Kapiti to Hutt).

    In a parallel and more sensible universe, North-South Junction double-tracking would have been funded by NZTA, and would have been given priority over the Northern Corridor motorways.
