Transmission Gully Highway and PCC Link Roads

Transmission Gully Highway

Transmission Gully Highway (TGH) is a four lane state 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. TGH 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 TGH and the connections to Kenepuru Drive and State Highway 58 are the responsibility of New Zealand Transport Agency (NZTA) and more information can be found on their website from the links below.

The connections to Waitangirua (Warspite Avenue) and Whitby (Navigation Drive and James Cook Drive) are via link roads that will be local roads administered by Porirua City Council.

Design and Construction of PCC Link Roads

Porirua City Council has negotiated a Design and Construct (D&C) contract with the TGH D&C contractors, Leighton HEB Joint venture (LHJV) to build the PCC Link roads in tandem with TGH.  It is a contractual requirement that the PCC link Roads will open for public use with Transmission Gully.

Design of the PCC Link Roads is scheduled to be substantially complete by November 2015 with the main construction (substantial earthworks etc.) commencing in 2016 with targeted completion in April 2020.

To assist PCC administer the D&C contract Opus International Consultants have recently been engaged as PCC’s “Principal’s Advisor” for the PCC Link Roads D&C Contract.

Design Features of PCC Link Roads

The PCC link roads from TGH 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.

The Whitby Link Road will connect to the existing roundabout at the intersection of Navigation and James Cook Drives.

The Waitangirua Link Road will intersect with Warspite Avenue opposite Niagara Street and be controlled by traffic signals.

Benefits and Effects of PCC Link Roads

  • 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.
