Motorways will be partially closed in several places over the next few days to allow for road works.
The closures start in Mt Roskill tonight, and will include routes to the airport and the harbour bridge.
Commuters also face further disruption as passenger trains are phased out of action across Auckland for the weekend, from 8pm tonight, so a new signals system can be turned on.
The Transport Agency will close the end of the Southwestern Motorway west of Dominion Rd for the weekend, starting after this evening's travel peak, as part of its four-week construction of a new interchange needed for the $1.85 billion Waterview connection project.
George Bolt Drive - the State Highway 20A route to the airport - will be partially closed over four nights from Sunday while it is resurfaced.
