Transmission Gully and Link Roads

Transmission Gully

Transmission Gully is a four lane highway to be built from Linden to McKay's Crossing (north of Paekakariki) passing through the rural areas to the east of Porirua and Whitby. Transmission Gully will provide a new route for State Highway One and will have connections to Porirua City's local roading system at Kenepuru Drive (near Bowland), Warspite Avenue (near Waitangirua Mall), the southern end of James Cook Drive and State Highway 58 just east of Pauatahanui.

The main Transmission Gully road and the connections to Kenepuru Drive and State Highway 58 are the responsibility of New Zealand Transport Agency and more information can be found on their website from the link below.

The connections to Waitangirua (Warspite Avenue) and Whitby (James Cook Drive) are via link roads that will be local roads administered by Porirua City Council. The current work on the link roads is the preparation of the information required for the "Notice of Requirement" for the designation of land for the link roads.

Final Report released

On 22 June 2012, the Board of Inquiry released its final decision on the Transmission Gully applications. The Board’s decision can be accessed on http://www.epa.govt.nz/Resource-management/tg/Pages/Final-report-and-decision.aspx.

The current timetable for the Transmission Gully project sees construction beginning in 2015 and completed by 2021.

Transmission Gully Link Roads

Council recently asked for submissions from the public, landowners, community groups and special interest organisations to help decide on its plans for two new roads linking Whitby and Waitangirua to the Transmission Gully Route.

Background

The Minister of Transport announced in late 2009 that Transmission Gully (TG) will be the future State Highway 1 route and is expected to be substantially complete within ten years. The link roads are an integral part of the Transmission Gully Project.

For further information see the NZ Transport Agency website.

Design Features

The link roads from Transmission Gully to James Cook Drive in Whitby and to Warspite Avenue/ Niagara Street in Waitangirua will be part of the Council network, designed for a 50kph operating speed, with no section steeper than a grade of 1:10. Various routing options were developed and after discussion with landowners the Council has selected preferred routes.

At the Warspite Avenue/Niagara Street intersection, a new roundabout will be required with sufficient land reserved for traffic signals and the possible future extension of Niagara Street as a link to Whitford Brown Avenue.

Where zoning allows future residential development beside the link roads the designation will allow for future footpaths, kerbside parking, entrance splays for residential roads and necessary services.

Benefits and Effects

  • The link roads will provide easier, faster access to Wellington, the Hutt and Kapiti Coast.
  • The Waitangirua Link will reinforce the role of the Waitangirua Village Centre as a focus for activity in the suburb.
  • The Whitby Link will strengthen the roles of James Cook Drive and Navigation Drive.
  • There may be noise, dust and runoff effects during construction which will need to be addressed by appropriate conditions of work.
  • There may also be landscape effects and possible effect on streams and other water bodies that will require careful management and design. The preferred routes have been selected to minimise the need to cross streams or reduce the impact by crossing high up catchments.
  • Where there is existing development beside the new road in Waitangirua consideration will be given to landscaping and noise protection fencing to reduce any effects.

Results of Consultation

A total of 34 submissions were received and were summarised in a report. The Council's Strategy, Finance and Regulatory Committee considered this report at its meeting on 29 April 2010 and Council approved the proposed alignments for the purpose of preparing the Notice of Requirement for the project on 12 May 2010. All submitters have been sent letters advising them of this and of the further work proposed on the matters of interest to them.
