Video: Manukau Extension Opening


You’ll be able to walk or cycle on the new SH20-1 Manukau Extension motorway, on Saturday week (August 28) before it’s open to traffic.

Pedestrians can try it out between 10am & 1pm, cyclists only 1pm - 2pm.

You enter from Lambie Drive and free buses will pick up and drop off between Cavendish Drive Interchange and Davies Avenue

The walking route spans 3.5 kilometres of the new motorway from Cavendish Drive Interchange to the SH1 underpass.

The $220M Manukau Extension motorway will be opened progressively up to December. The new 4.5 kilometre-long extension will have two lanes in each direction and connect the Southern and Southwestern motorways. ute will provide a 48 kilometre alternative to SH1 between Manukau and Albany via SH20, SH16 and SH18.

NZTA has done this video about it with Ruben Wiki!

The day after the walk, the first part will open - that will be the SH20 southbound lanes. Once opened motorists heading south to Roscommon Road will need to exit SH20 at the Puhinui Interchange and use the new connecting road through to Cavendish Drive Interchange.
The second stage - the SH20 westbound lanes - will open December: The remaining local road changes will be completed and the motorway will be fully open.
Here’s another NZTA video about the Western Ring route:

    Jon, do you know what intersection is in the first photo?

  2. Jon C says:

    @Owen Cavendish Drive interchange

  3. Patrick says:

    I was driving around there this afternoon and there is still a lot of work to do for the September opening. I guess once the earth works are finished the roads don’t take long to lay.

  4. karl says:

    Do they ever explain why according to NZTA, on a 3m wide shared path is okay to mix pedestrians and cyclists, but on a motorway of at least 9 meters clear width at the very least, it is a danger? Don’t get that. OSH run wild.
