Motorists traveling along the M1 Pacific Motorway in New South Wales are facing significant delays following an incident on the Hawkesbury River Bridge at Mooney Mooney that has forced emergency repair works and lane closures.

The disruption has affected northbound traffic, with two of the bridge’s three northbound lanes currently unavailable while crews work to address the issue. The reduced road capacity has resulted in heavy congestion, with long queues forming as drivers approach one of the region’s busiest transport routes.

Traffic conditions have deteriorated throughout the area, with delays extending several kilometers south of the bridge. Motorists heading toward the Central Coast and northern parts of New South Wales are being advised to allow extra travel time as emergency crews continue working at the scene.

Emergency Crews Respond Following Bridge Incident

Authorities have confirmed that emergency road repairs are underway after an incident occurred on the Hawkesbury River Bridge. While specific details about the incident have not been fully released, repair teams have been deployed to assess the situation and complete the necessary works to restore safe travel conditions.

The closure of two northbound lanes has significantly affected traffic flow, forcing vehicles into a single operational lane. With thousands of motorists normally relying on the three-lane crossing, the restriction has created a major bottleneck and contributed to widespread delays.

Road crews and traffic management personnel remain on-site, working to safely manage the situation while repairs are carried out. Drivers are being reminded to follow instructions from emergency workers and temporary traffic controls in place around the affected area.

Heavy Congestion Impacts M1 Travelers

The M1 Pacific Motorway is a major transport connection linking Sydney with the Central Coast, Newcastle, and surrounding regions. Because of the high volume of vehicles using the route every day, incidents on the Hawkesbury River Bridge can quickly create significant disruptions.

Current traffic conditions have seen motorists experience slow-moving traffic and stop-start conditions approaching the bridge. Many drivers have reported longer-than-normal travel times as vehicles merge into the remaining open lane.

The congestion is affecting a wide range of travelers, including daily commuters, freight operators, commercial vehicles, and holiday traffic moving through the region.

Authorities Issue Safety Advice

Transport officials are urging motorists to remain cautious while traveling through the affected area. Drivers are encouraged to:

  • Reduce speed when approaching the repair zone.
  • Follow directions from traffic controllers and emergency personnel.
  • Maintain safe distances between vehicles.
  • Allow additional time for their journeys.
  • Check traffic updates before beginning travel.

Authorities have emphasized that protecting motorists and road workers remains the highest priority while repair activities continue.

Regional Travel Disruptions Expected

The Hawkesbury River Bridge is a critical part of the M1 Pacific Motorway network, and any interruption can have a significant impact across the surrounding road system.

With limited northbound lanes available, traffic management teams are closely monitoring conditions and making adjustments where necessary to reduce congestion. However, delays are expected to continue until repair work is completed and additional lanes can safely reopen.

Motorists who have flexibility in their travel plans are encouraged to consider delaying their trips or allowing extra time to avoid the worst congestion periods.

Updates Awaited as Repairs Continue

At this stage, authorities have not provided a confirmed timeframe for when all northbound lanes will reopen. Crews will continue assessing the situation and carrying out repair work until the bridge is safe for normal traffic operations.

Drivers are encouraged to remain patient, stay informed through official traffic updates, and exercise caution while passing through the affected section of the motorway.

The M1 Pacific Motorway remains open, but motorists should expect ongoing delays near the Hawkesbury River Bridge at Mooney Mooney until emergency repairs are completed and normal traffic flow is restored.
