Motorists should expect delays and congestion after a four-vehicle crash on the Southern Motorway this afternoon.
All lanes are now open but traffic is heavy in both directions after the pile-up.
Three people were injured after three cars and a truck collided just north of Princes St heading into the city at 12.20pm.
The truck was on its side, straddling two lanes.
A Fire and Emergency spokesman said three people were injured, but none seriously.
