Bridges are critical to the transportation system especially at the time of crises. They are essential for rescue missions, evacuations, and rapid distribution of aid and medical supplies. Bridges are highly visible and accessible structures which make them valued potential targets for terrorist attacks as their destruction could have significant impact on the nation. An efficient security system can minimize the potential of terrorism, yet it will not completely eliminate the threat. Consequently, critical bridges should be protected and designed to mitigate probable blast hazards.
