There will be added congestion for commuters from the west and northwest of Auckland for the start of the work week with motorway lanes closed.
A section of the city-bound right-hand lane of the Northwestern Motorway, between the Royal Road on-ramp and the Lincoln Rd off-ramp, will be shut from tomorrow until March 2018.
It will leave two lanes open for the busy stretch.
The third lane will become available after the Lincoln Rd off-ramp.
The New Zealand Transport Agency said the closure is to create a safe work area for a construction team to widen the motorway, while keeping traffic moving,
It said it would also allow for piling work for the new Huruhuru Bridge, which is being raised to provide more clearance for freight and other high vehicles.
