The Convict Bridge located along the Great Western Highway, a critical route between Sydney and New South Wales' Central West, has been shut down for at least two weeks following the discovery of cracks and structural movement. Transport for New South Wales (TfNSW) authorities took immediate action to close the bridge in both directions after assessing the potential risk to motorists and minimizing any safety hazards. Experts are now conducting geotechnical investigations to determine the underlying causes of the detected instability, which is a significant concern given the bridge's historic status dating back to the 1830s.

As a result of the bridge's closure, all vehicles that typically traverse this popular highway route are being diverted, leading to increased congestion on alternative routes, particularly through Lithgow via the Bells Line of Road and Chifley Road. This diversion is expected to pose challenges for commuters and trade in the region, potentially disrupting daily travel patterns and impacting local businesses. Authorities are working to communicate the changes to the public effectively to mitigate any inconveniences during the maintenance period.

TfNSW has emphasized the importance of safety while addressing the urgent need for repairs and assessments of structural integrity. The investigation will involve drilling into the bridge to ascertain the extent of the damage and determine a plan of action for repairs. The outcome of this investigation will dictate how long the closure will last, as the safety of the traveling public remains the highest priority for New South Wales transport officials.
