The Harbour Bridge and Loch Lomond Road were the scenes of two separate car collisions.
Everyone involved in a two-vehicle crash on the Harbour Bridge walked away unhurt, but platoon chief Joe Armstrong says that traffic on the bridge slowed to a crawl as emergency crews responded. He says that the second crash they responded to on 665 Loch Lomond Road also involved two vehicles, and nobody was hurt.
In both collisions, small amounts of motor vehicle fluid spilled onto the street.
