The project starts north of the Mackays Crossing overbridge, on the four lane length of State Highway 1 known as the Raumati Straights. The first 2km involves rehabilitation of the existing roadway, to Expressway standard and will eventually tie into Transmission Gully. The new Expressway starts just south of Poplar Avenue. It involves:
Building the Poplar Avenue partial interchange with south facing on and off ramps only
An overpass over Raumati Road
Converting Leinster Avenue to a cul de sac
Building a new local road off Leinster Avenue to provide access for properties cut off by the Expressway
A bridge over the Wharemauku Stream, where provision is being made for a floodway and pedestrians and cyclists
A full interchange at Kāpiti Road with both north facing and south facing on and off-ramps controlled by traffic lights
Widening Kāpiti Road to provide two through lanes in each direction and turning lanes.
A lot of people live close to this area of construction, so noise, dust and vibration are carefully monitored. Also, regular neighbourhood forums continue to be held with local residents to talk through any issues or concerns.
From Kāpiti Road, the Expressway continues through Paraparaumu to Waikanae. Largely it follows a route that was held for many years for a Western Link Road. The construction of this section involved:
Lowering Mazengarb Road in Paraparaumu to allow the Expressway to pass over it
Creating major new wetlands
Building a bridge over Otaihanga Road
Reinstating access to private properties
Building the four-lane, 180m Waikanae River bridge, the largest single structure of the project.
The four-lane Waikanae River Bridge is the biggest single structure on the new Expressway. The bridge has been architecturally and seismically designed, pushing engineering design and innovation to their limits. It boasts the biggest bored piles in New Zealand.
The project worked with local iwi, Te Atiawa, on the urban design details of the new Waikanae River Bridge.
Many people live next to construction in the Central Zone. Noise, vibration and dust were carefully monitored. Also, regular neighbourhood forums continue to be held with local residents to talk through any issues or concerns.
From the Waikanae River Bridge, the Expressway continues through Waikanae where it connects to local roads via a full interchange at Te Moana Road. It then continues to just north of Peka Peka Road where it re-joins the existing highway.
Construction in this zone involved:
The area between the Waikanae River and Te Moana Road is waahi-tapu, sacred Maori land. The project team worked respectfully in this area, observing certain cultural protocols such as eating only in blessed areas.
As in other zones, work was close to people’s houses and businesses. Regular neighbourhood forums continue to be held with local residents to talk through any issues or concerns.
