MYTH #2: That the Matakana link road will fix Hill Street congestion.

The New Zealand Transport Agency (NZTA) and Auckland Transport (AT) have announced that the design of the Matakana Link is underway and they claim that it will ease the traffic problem at the Hill Street Intersection. They are suggesting that construction may be complete by 2022. There has been no commitment to extend the link to Sandspit Road.

TRUE: It might help with some of the holiday traffic to Matakana and Omaha but less so for Snells Beach.

TRUE: It might take a few commuters to Auckland. How many people do commute and what happens to their families?

FALSE: The families still need shops and schools and medical services and building supplies and building contractors and these still need to drive through the Hill Street Intersection. As urban growth occurs all these activities will increase.

FACT: The link road will be a collector road, which means that it won't just provide for traffic between State Highway 1 and Matakana Road but also collect the traffic from the 2200 new dwellings along its course.

PROOF: Our traffic surveys for a typical midday peak are shown below. Judge for yourself.

EXPLANATION: There are three ways the Matakana Link will change traffic patterns:

  1. There will be new intersections on State Highway 1 and Matakana Road, which interrupts the existing flow along that road;

  2. There will be more southbound traffic on Matakana Road between the new intersection and Sandspit Road; and

  3. The new road and adjoining Northern Growth Cell (2200 additional dwellings) will generate construction and local traffic.

New Intersections

Any new intersection along State Highway 1 or Matakana Road will interrupt the steady flow of traffic in some way. Whether it is a t-shaped controlled intersection or roundabout, through or turning traffic will be affected.

Remember, there will already be a new tollway/State Highway 1 intersection. Within an 800 metre stretch of State Highway 1, there will be three major intersections - at Hudson Road, the Matakana Link Road, and the tollway. Currently, there are four sets of traffic lights through Warkworth and two more intersections will increase journey times.

Sandspit Road bound traffic

More traffic uses Sandspit Road than Matakana Road. One of the major conflict points is right-turning traffic into Sandspit Road crossing the path of southbound Matakana Road traffic.

The Matakana Link will increase Matakana Road traffic turning left into Sandspit Road. Whilst currently that traffic has to give way to right-turning traffic onto Sandspit Road, left-turning traffic still has to queue behind Matakana Road through traffic heading towards the Hill Street intersection.

A collector road

The link road won't be a bypass in the purest sense. It will be a local collector road, meaning that any properties neighbouring it will be able to have accessways onto it.

The Auckland Unitary Plan has zoned the land around the link road as a "Northern Growth Cell", accommodating potentially 2200 additional dwellings. Potentially, construction traffic and local traffic using the link road and connecting
