🚚 Northbound B-double Breakdown Snarls M11 in Pennant Hills

A B-double breakdown has caused significant disruptions for northbound motorists on the M11 Motorway (NorthConnex) in Pennant Hills this morning. Transport for NSW reported that the incident, classified as an unplanned breakdown, has led to the closure of Lane 1 of two available lanes, impacting traffic flow in the area.

Motorway Crew personnel are currently on the scene to manage the situation and assist with the recovery of the heavy vehicle. Drivers travelling through the Pennant Hills area are advised to reduce their speed and exercise caution, with potential delays expected. The M11, known as NorthConnex, is a vital 9-kilometre twin-tube motorway tunnel in northern Sydney, bypassing the often-congested Pennant Hills Road. It connects the M1 Pacific Motorway at Wahroonga to the M2 Hills Motorway at West Pennant Hills and is renowned as one of Australia's longest and deepest road tunnels, assigned the route number M11 in 2023.

B-double trucks, like the one involved in today's incident, are substantial vehicles that play a crucial role in freight transport across Australia. These combinations can stretch up to 25 metres in length (or 26 metres under specific conditions) and carry a gross mass of up to 62.5 tonnes. The M11 Motorway forms an integral part of the National Highway route, with heavy vehicles, including B-doubles, generally mandated to use the NorthConnex tunnels when travelling between the M1 and M2, rather than Pennant Hills Road.

NorthConnex is equipped with a dedicated Incident Response team that operates 24/7, ready to attend to breakdowns and other incidents within the tunnel system. Emergency barriers and warning signs can be activated at tunnel entry points to ensure motorist safety during such events. Travellers are encouraged to check live traffic updates before heading out.
