The NZ Transport Agency says all three westbound lanes of Auckland’s Northwestern Motorway (State Highway 16) have now re-opened.
Two of the three lanes were closed early this morning when a gantry sign over the motorway was accidently hit by a machine installing safety barriers along the edge of the motorway.
No one was injured in the accident, which occurred 500 metres west of the Great North Road interchange.
The Transport Agency says there may be some delays for westbound travellers while congestion clears. Eastbound lanes on the motorway were not affected.
