On 23 March 2007 an accident occurred in the Burnley Tunnel Melbourne which links commuters between the city and eastern suburbs. A truck stopped in the left lane due to a blown tyre. This notified City Link monitoring control centre who activated a closed lane signal and reduced the tunnel speed limit. The accident occurred when a truck ran into cars trying to drive around the stationary truck, setting off further collisions. One of the trucks burst into flames on impact causing a large fire and explosions.

Three people were killed and two injured. Evacuation of hundreds of commuters was necessary and the tunnel remained closed for several days.
