STORY: Eleven people were arrested, including the woman who police said allegedly put a bicycle lock around her neck and the steering wheel of a vehicle that was blocking all city-bound lanes. The vehicle has since been removed.
Dozens of members of Blockade Australia, a climate activist group, moved across major roads causing peak-hour traffic chaos for motorists and pedestrians. Television footage also showed some people throwing garbage bins on the road.
Police estimated about 60 people were part of the protest.
