Commuters on Auckland's northwestern motorway can expect significant changes from Monday as part of the Western Ring Route development.
Closures include the eastbound bus shoulder lane from the causeway bridge to the Great North Rd off-ramp for three years.
It will extend the existing 700 metre area already off limits.
The eastbound bus shoulder lane from the Whau River bridge to the Patiki Rd off-ramp will also be closed for two years.
From Wednesday, 400m of the westbound bus shoulder lane along the causeway to the Rosebank Rd off-ramp will be closed for three years.
Also, from early October the 400m westbound bus shoulder lane from the Great North Rd on-ramp merge to the Causeway Bridge will be closed for three years.
NZ Transport Agency highways manager Tommy Parker said the changes will have a significant impact on people using the route.
"Even with six lanes of motorway the corridor is very narrow and space is at a premium. With our work ramping up we need these shoulder lanes to give our workers the room they need to do their job safely.
"New bus lanes are expected to open in stages from 2015 as the project progresses."
Mr Parker says that in the next few weeks the agency will introduce measures to manage the impact of the work and help people stay connected with developments.
He says one option for northwestern regulars is to leave the car at home and take the bus so fewer vehicles are using the highway.
The Causeway Upgrade Project is one of a series of projects to complete the Western Ring Route connecting the northwestern and southwestern motorways targeted for 2017.
