Transmission Gully gets the green light
Transport Minister Steven Joyce has welcomed the green light for the development of Transmission Gully, which will be
the largest single project in the Wellington Road of National Significance.
The announcement was made by the NZ Transport Agency today as part of the plan for a strategic roading upgrade of State
Highway 1 between Wellington and Levin which will reduce congestion, improve safety and support economic growth.
Once complete, the upgraded route from Wellington Airport to Levin is expected to deliver travel time savings of between
23 and 33 minutes during peak times and between 17 and 23 minutes during the day.
Following the 2008 election the Minister said he was not prepared to support funding for the proposal until he had seen
a thorough assessment of Transmission Gully alongside the alternative Coastal Route.
Mr Joyce says Transmission Gully has been debated for decades but this is the first time a decision has come with the
plan and the funding track to see it through.
“The Government’s decision to invest nearly $11 billion in new State Highway Infrastructure over the next ten years will
ensure funding is available for the gully project.”
The NZTA is investigating the possibility of tolling the route as a means to bring construction forward.
“The gully route is the best long-term option for the State Highway 1 Road of National significance between Wellington
and Levin in terms of route security, journey time savings and minimising impact both during construction and in the
longer term.
“Proponents of the coastal route generally support it because of perceived lower costs. However the latest cost
estimates show a similar cost profile between the two options with bypasses at Pukerua Bay, Plimmerton and Paremata
being particularly costly because of the built-up nature of those areas, and the widening of Centennial Highway also
being problematic.”
Mr Joyce says an important factor in the NZTA’s decision making was the need to minimise the impact on existing
communities.
“Transmission Gully will bring benefits to the coastal communities of Mana, Plimmerton, Pukerua Bay and Paekakariki
through reduced community severance and traffic noise, as well as improved air quality.”
Transmission Gully will also provide an improved east/west connection, with a better and more direct link to State
Highway 58, the Hutt Valley and the Wairarapa.
Another strong argument for the Gully route is that it provides an alternative route out of Wellington in the event of a
major earthquake or other disaster.
“In a city like Wellington that is so vulnerable to a big quake, you’ve got to have route security,” says Mr Joyce.
“Progressing the Coastal Route would have meant putting all our eggs in one basket.
“Make no mistake, at about a billion dollars this is a very expensive project, so the project is likely to need both the
government funding and tolling. The geography of the area means that there are no cheap or easy options.”
Mr Joyce says he thanks local communities for their patience while a final decision was reached and looks forward to now
getting on and improving roading for the whole area.
