| 摘要： | In 1967, the Interstate 35W Mississippi River Bridge in Minneapolis opened to traffic. The bridge was 1,907 feet long, had 14 spans, and by 2007 carried a daily average of 140,000 total vehicles north and south over four lanes between University Avenue and Washington Avenue. The vehicle count made it one of the busiest bridges in the country over the Mississippi River, and one of three principal arteries into downtown Minneapolis, a city with one of the highest population densities in the Midwest. Just after 6 p.m. on the evening of August 1, 2007, the 40-year old bridge collapsed into the river and its banks without warning, killing 13 and injuring 121 others. At the time, there were approximately 120 vehicles, carrying 160 people, on the bridge. The impact of the fall broke the span into multiple planes of broken steel and crushed concretecars, buses, and trucks all resting precariously along guardrails or suddenly unprotected edges, crashed into other vehicles, partially embedded in the muddy river bank, or dropped precipitously into the river. The most urgent task was rescuing people from the water and from their vehicles, conducting triage on the injured, and providing transport to area hospitals. Several vehicles were on fire, making firefighting operations a parallel priority. Local and State staff and officials from fire, law enforcement, emergency management, and public works received immediate alerts and, having trained together in classroom settings and through field exercises, knew what to do and with whom they needed to coordinate their response. Years of investing time and money into identifying gaps in the citys disaster preparedness capabilities; acquiring radios for an interagency, linked 800 MHz system; and participating in training on the National Incident Management System (NIMS) and on the organizational basis for that system (the Incident Command System (ICS) and Unified Command) paid off substantially during response and recovery operations. / NOTE: Technical rept. series. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
