The main deck of the Sydney Harbour Bridge was opened to pedestrian traffic today. Approximately 250,000 people walked across the bridge southward from Milsons Point or North Sydney towards the center of Sydney.

Avalias CrowdFlow was used to simulate pedestrian dynamics and test crowd management plans for the Sydney Harbour Bridge 75th Anniversary Bridge Walk event.

Congratulations to the organizers of the event - this is an example of excellence in major event planning.
