A section of Auckland's Northwestern Motorway is being closed at nights during the next two weeks while a bridge is repaired.
The closures begin on Tuesday and will affect city-bound lanes from the Brigham Creek roundabout to the Royal Road overbridge.
The bridge was damaged last week when it was hit by a digger being carried on a truck. It remains open, although a 30 km/h speed limit is in place.
Repairs will be carried out between 10pm and 5am from Sundays to Thursdays.
It is expected they will be completed by 15 May.
