Sydney Harbour Tunnel Fire Update — A vehicle fire broke out in the southbound lane of the Sydney Harbour Tunnel at about 8 a.m. on Wednesday, August 26, prompting an emergency response and the closure of the tunnel in both directions.
Fire and Rescue NSW received a Triple Zero call reporting the vehicle fire, after which three fire trucks were dispatched to the tunnel. The tunnel’s automatic sprinkler system also activated as emergency crews responded to the blaze.
Firefighters were able to extinguish the vehicle fire. The damaged car was subsequently scheduled to be towed from the tunnel as authorities continued recovery and safety operations. One person was assessed for possible smoke inhalation, while no further serious injuries were reported in the initial information available.
The incident caused significant traffic disruption around the Sydney Harbour crossing. Traffic on the Gore Hill Freeway was reported to be backed up beyond Artarmon, while congestion was also building on the M1. Motorists approaching from the north were also experiencing delays, with traffic backing up toward Mosman.
Motorists were advised to avoid the Sydney Harbour Tunnel while emergency crews completed their response and recovery work. Drivers needing to cross Sydney Harbour were encouraged to consider the Sydney Harbour Bridge as an alternative route where possible.
The tunnel was closed in both directions to provide emergency crews with sufficient space to extinguish the fire, assess the area and remove the damaged vehicle. Authorities may also need to check for smoke, damage and other potential hazards before reopening the tunnel to traffic.
The automatic sprinkler system’s activation formed part of the tunnel’s built-in fire-safety response, helping to control the fire as firefighters attended the scene. Authorities have not indicated that the incident was suspicious, and the available information does not establish what caused the vehicle to catch fire.
The fire has been extinguished, but traffic conditions remain disrupted while the vehicle is removed and the tunnel is assessed for reopening. Motorists should avoid entering the closed tunnel, follow directions from emergency personnel and traffic controllers, and check official traffic updates before travelling through the area. Drivers should allow additional time for their journeys while traffic gradually returns to normal.
