Motorists traveling northbound on the M1 Pacific Motorway are experiencing significant delays following an incident that has prompted emergency road repairs on the Hawkesbury River Bridge at Mooney Mooney. Traffic authorities have confirmed that two of the bridge’s three northbound lanes are closed, leaving only one lane open to traffic. The reduced capacity has caused heavy congestion, with long queues extending several kilometers south of the bridge and slow-moving traffic reported toward Cowan.
Emergency crews and road maintenance teams remain on-site carrying out repairs to ensure the bridge is safe for motorists. While officials have not released full details about the incident that led to the repair work, they have emphasized that the restrictions are necessary to maintain public safety. The M1 Pacific Motorway is a major transport route connecting Sydney with the Central Coast, Newcastle, and northern New South Wales. As a result, the lane closures are affecting commuters, freight operators, and holiday travelers, leading to extended travel times throughout the area.
Authorities are urging drivers to exercise caution by reducing speed, following traffic management instructions, maintaining safe distances, and allowing extra time for their journeys. Motorists are also encouraged to check live traffic updates before departing and consider adjusting travel plans where possible. There is currently no confirmed timeframe for when all northbound lanes will reopen. Traffic officials continue to monitor conditions and will provide updates as repair work progresses. Delays are expected to continue until the emergency repairs are completed and normal traffic flow is safely restored.
