Description

The NZTA's project to upgrade SH2 between Dowse Drive and Petone includes:

  • Construction of a grade-separated interchange with a roundabout over SH2 at Dowse Drive with a connection to Hutt Road and Dowse Drive.
  • Construction of an overbridge to replace the traffic lights at Korokoro connecting Petone and Korokoro.
  • Upgrading the section of SH2 between Korokoro and the Petone overbridges by providing a safety barrier to separate north and southbound lanes.
  • Rearranging and improving Petone Railway Station's existing Park and Ride carpark facilities including providing an access bridge over SH2 and upgrade of the footbridge.
  • A new service road between Cornish Street and Korokoro providing access to the industrial area.
  • An upgrade of the Percy Scenic Reserve access and parking facilities.

These plans and the options considered were developed through a public consultation programme.

The area involved in this project included the section of SH2 from Dowse Drive to north of the Petone overbridges and local roads including Hutt Road, Dowse Drive, Korokoro Road and London Road.

The Dowse Drive to Petone section of SH2 is bounded by severe physical and operational constraints. Along its western edge, the route is located along the scarp of the Wellington Fault (also referred to as the “western escarpment”). To the east, the Wairarapa and Melling Branch railway runs the full length of this section of the highway. The section of SH2 between Korokoro Intersection and the Petone overbridges runs through an industrial area and is referred to in this project as the Korokoro Industrial Area (KIA).
