A multiple-car crash on the Northern Motorway near Greville Rd is blocking the right-hand lane.

It is adding to a nightmare morning for city-bound commuters, who now face a 65-minute drive from Greville Rd to Fanshawe St.

An earlier crash just north of the Auckland Harbour Bridge has now been cleared.

Meanwhile, a car has broken down near Mangere Bridge on the northbound lanes on the South Western motorway. Lane three is blocked and motorists are urged to drive carefully.
