That should provide ample room for pedestrians as well as cyclists, who will also gain their own protected pathway down the western side of Nelson St to Victoria St.
But they will have to cross at traffic lights to the opposite of Nelson St to continue to the waterfront in a second stage of the project, to be completed next year.
Auckland Council, which is contributing $2.55m to the project against Government funding of $11.35m, has issued the artist's impressions after a survey in which 862 people had their say over the cycleway's design.
They rejected "motorway grey" in favour of a bright and bold design which would be "distinctly New Zealand."
Councillor Chris Darby, Auckland's designed political urban design champion, said today that the project "shines a light on walking and cycling and offers an inspiring new way through a previously impenetrable Spaghetti Junction."
"It offers a seamless walk-across-the-rooftops connection into the city centre, with sweeping views of the city and harbour."
