People living and working on the Kāpiti Coast can now use the Expressway, or continue to use the original State Highway 1* to travel between the town centres and around the district.
The links on this page will take you to information about how the Expressway interchanges work with the local road connections and how traffic uses them to get on or off the Expressway at those points.
*Within two years of Expressway opening, the stretch of existing State Highway 1 between Poplar Avenue in Raumati South and Te Kowhai Road in Peka Peka will no longer be required to operate as a state highway. It will become a fit-for-purpose local road.
A regional connection
The design decisions about all the Expressway’s interchanges were made as part of the consent process before the construction work started. Those planning decisions had input from a range of stakeholders, including the Kāpiti Coast District Council, and were made by the Environmental Protection Agency’s Board of Inquiry on the Transport Agency’s application to construct the Expressway.
Getting on and off
There are two places on the 18km Expressway route where traffic can get on and off in both directions. Local traffic can choose to use these interchanges (at Kāpiti Road and Te Moana Road), as well as the existing State Highway 1 route (which will become a local arterial road once the Expressway opens), for regional journeys.
Poplar Avenue and Peka Peka have partial interchanges. This decision was made largely due to the Expressway being designed to operate as a regional rather than a local connection. The decision also recognised that the existing state highway should become safer and more reliable for local traffic when the Expressway opens.
Another consideration was around managing urban development along the Expressway route. An assessment of traffic impacts was done as part of this process.
What is an interchange?
An interchange is a grade-separated intersection, usually where one road passes over another, with ramps to connect them. They’re designed to get you on and off expressways smoothly. Interchanges connect with key roads on the local road network and a lot of study and collaborative planning has gone into where these connection points should be. They help to get trucks and other through-traffic on and off local roads as efficiently as possible.
The Mackays to Peka Peka Expressway has four interchanges; two full and two partial. A partial interchange is where you can get off the Expressway in one direction, and onto it from the other. A full interchange is where you can get on and off in both directions.

A shared pathway
As well as providing a long-awaited connection for motorists, the Mackays to Peka Peka Expressway has delivered a unique community asset that offers improved cycling, walking and horse riding facilities on the Kāpiti Coast. Find out more.
