The next stage of the western ring route project is under way with the contract awarded to an Australian company.
Sydney-based Leighton Contractors will head the $70 million upgrade of the northwestern motorway between the St Lukes and Great North roads interchanges.
It will be jointly-funded by the New Zealand Transport Agency and Auckland Transport.
A 2-kilometre section of the motorway will be widened from three to four lanes in each direction.
The St Lukes Rd overbridge spanning the motorway will be widened to benefit drivers, walkers and cyclists.
NZTA highways manager Tommy Parker says this is the last of six projects to connect the northwestern and southwestern motorways.
"The upgrade is part of our programme to get our network ready for the increased volume of traffic when the Waterview tunnels connecting the northwestern and southwestern motorways are completed in early 2017."
Work is due to start in mid- autumn and be completed by late 2016.
The route will provide a 47km-long alternative to State Highway 1.
