Disaster Response Route

Disaster Response Route (DRR) is a network of pre-identified municipal and provincial roads in the Province of British Columbia, Canada that can best move emergency services and supplies to where they are needed in the event of a major disaster. These roads are part of the Coordinated Regional Emergency Transportation Strategy and are intended for emergency responders when a disaster strikes and are not evacuation routes for the public.
History.
DRR came upon to the Province after witnessing the traffic mayhem after disasters like the 1989 San Francisco, 1994 Los Angeles earthquakes, September 11 terrorist attack. It was decided that BC will require a system to control post-disaster traffic and BC became the first jurisdiction in the world to implement a disaster response road plan in 1995. In the original plan, only Vancouver roads were considered but eventually expanded to marine routes, railways and air transports.
DRR roads are capable of withstanding natural disasters and the roads all link to Abbotsford, more specifically to Abbotsford International Airport. While DRR consists mostly of roads, emergency plans also includes marine routes suitable for quick access for responders.
There were confusion since the launch of the program with the general public - the original sign did not include the third tab (Emergency Vehicles Only During a Disaster) which led many to believe these roads are for evacuation when disaster strikes. Since 2004, the Ministry of Transportation added the third tab and increased public awareness to promote the correct use of these roads during a disaster.
Operation.
Roads that are pre-marked as DRR are open to the general public unless a state of emergency was declared by the municipal or provincial government. Once a state of emergency is declared, DRR can be activated and the local police will be responsible for cordoning off the roads. As soon as possible, the public will be allowed back onto the Disaster Response Routes.
DRR is intended for those who have the following function to access the roads within 72 hours of a disaster strikes:
Specifically, 'DRR users' are categorized into 3 groups:
Once activated, only those who have been issued with DRR hangers (for automobiles) or DRR decals (on Driver's license, employee ID or government IDs) will be able to access the designated roads.
