Lengthy traffic delays and congestion followed an accident on the Sydney harbour bridge on Thursday afternoon.
Three cars collided around 3pm (AEDT) on Thursday near the north pylon of the bridge, causing one of the cars to crash into the pylon.
AAP reports a woman, two men and a baby were trapped in vehicles for some time before they were taken to hospital in a stable condition.
There was considerable congestion in the CBD, with only one northbound lane and two southbound lanes open while emergency services worked to free them.
Even after the lanes reopened, the gridlock continued well into peak hour, with huge queues in southbound lanes. Buses leaving Circular Quay were running 20 minutes behind schedule.
NSW Transport Management Centre advised commuters to take trains or ferries wherever possible.
It was not until 7.30pm that traffic was flowing freely again on the bridge.
