Multiple outlets report that a major green bridge is closed to traffic for a police operation. The bridge is shut down just before 6:20am, according to coverage from Sydney, Brisbane and Melbourne. All sources state that the closure lasts more than two hours, with the bridge remaining closed throughout the morning period covered by their reporting. While the articles agree on the timing and duration of the shutdown, they provide limited additional operational detail in the excerpts provided. The reporting is consistent that the closure is carried out as part of police activity and that motorists face disruption during the closure window. As of the end of the stated reporting periods, the bridge is still described as closed for the operation and then resumes later than the initial shutdown, though exact reopening times are not specified in the provided summaries. Overall, the accounts align on when the bridge closes and how long it remains unavailable to traffic.
