Truck Crash Closes Auckland's Southern Motorway

All lanes have been reopened on Auckland's southern motorway after a rubbish truck hit an overbridge this morning.

The New Zealand Transport Agency said State Highway 1 at Ellerslie was now open to traffic but motorists should expect long delays with queues stretching back to the city.

Rubberneckers were also causing delays for northbound traffic.

The agency recommended traffic heading south from the North Shore to consider using a longer route around State Highways 18, 16 and 20.

The New Zealand Transport Agency earlier tweeted the motorway was closed at Ellerslie because of a truck crash.
