Purpose

The Mackays to Peka Peka Expressway main alignment was completed four months early, with the road opened to traffic on 24 February 2017.

The Expressway delivers a key section of the Wellington Northern Corridor, a long needed upgrade of State Highway 1 north of Wellington. This highway is a critical link to the lower North Island and key regional destinations because the existing highway (soon to become a local road) does not serve its users well. It has a poor safety record, is vulnerable to closures by storms and crashes, and drivers are often caught up in nose-to-tail traffic.

The upgrade was required to provide safe, efficient and reliable access to and from New Zealand’s capital and third-largest city. It was also needed to support expected residential and business growth throughout the Wellington region.

Benefits

  • Reduced congestion on local roads as traffic is transferred to the Expressway.

  • Shorter and more reliable travel times for Expressway traffic by avoiding urban traffic lights and speed limits.

  • Modern road design resulting in safer trips to and through Kāpiti.

  • Improved access to Wellington's port, CBD, interisland ferry terminals, airport and hospital.

  • Kāpiti residents and businesses the first to benefit from the Wellington Northern Corridor improvements.

  • A second route and a more resilient road network in the event of crashes or natural disasters.

  • More jobs and better access to jobs in Kāpiti and beyond.

  • Innovation in the way the project is being delivered is setting new standards for the construction industry in New Zealand and beyond.

Key features

  • Two traffic lanes in each direction separated by a median safety barrier.

  • 18 new bridges including a new crossing over the Waikanae River.

  • Connections to local roads at Poplar Avenue (Raumati), Kāpiti Road (Paraparaumu), Te Moana Road (Waikanae) and Peka Peka Road.

  • Safety improvements on many local roads in the vicinity of the Expressway.

  • An end-to-end shared pathway next to the Expressway for pedestrians, cyclists and horses in some sections.

  • Environmental protection and enhancement including 140 hectares of new planting and landscaping, creation of 9.5 hectares of new or restored wetlands and 1.4 million locally eco sourced plants.

  • Archaeological investigations and monitoring over the life of the project.

  • Delivery by an alliance that has brought together the best team for the job.

  • New jobs and local procurement.
