Eastern Transport Corridor

Historically, it was to provide the route for an additional motorway connecting through the isthmus from the east into the Auckland CBD, with an estimated cost of up to $4 billion,[2][3] but political and local community resistance made the project fail in the 2000s.

The Purewa Creek section was to be aligned on an elevated expressway to avoid damage to the environmentally sensitive area, while the motorway would be sunk into trenches in Glen Innes to reduce disruption.

[7] However the impacts were still high, and the costs rising (with a worst case estimate of NZ$3.9 billion),[3] and at that point the corridor was fast becoming a political boondoggle.

[citation needed] However the transport reserve remains in place, allowing for the motorway to be undertaken at some point in the future if it becomes economically and politically feasible.

The new roads and public transport links were to serve intensified residential and mixed developments like the Mount Wellington Quarry area.
