Commuter chaos ensued in Wellington after a three-vehicle crash on the Johnsonville-Porirua Motorway at 6.44am.
All the cars have been towed and all lanes on SH1 Linden have reopened, the Transport Authority said.
Police said there were no injuries.
Motorists are being warned of congestion as traffic starts to flow.
Earlier on Wednesday, the right southbound lane at Linden south of the Kenepuru interchange was blocked for nearly two hours.
Queues were backed up to the Mungavin Interchange.
Meanwhile, police said there had been another single vehicle crash just north of the Johnsonville turn-off.
There were also no injuries in that crash and it was now clearing.
