![]() 2007 Complete Guide to the Minnesota Bridge Disaster - Collapse of the I-35W Mississippi River Bridge in Minneapolis, August 2007, Documents, Reports, Investigation (CD-ROM) $19.95 This comprehensive electronic book on CD-ROM provides an up-to-date collection of reference sources on the tragic collapse of the 1-35W bridge over the Mississippi River in Minneapolis, Minnesota. At 6:05 P.M. EST on Wednesday, August 1, 2007, the bridge (known as Bridge #9340 or the Squirt Bridge) over the Mississippi River between University Avenue and Washington Avenue on highway I-35 W in Minneapolis, MN, collapsed. Numerous vehicles were on the bridge at the time. At least eight people were killed in the disaster. The federal Department of Transportation issued an immediate notice to State Transportation Agencies and other bridge owners requesting an immediate re-inspection of all steel arch deck truss bridges with fracture critical members. At a minimum, State Transportation Agencies and other bridge owners should review inspection reports, including those for routine, in-depth, fracture critical, and underwater, to determine whether more detailed inspections are warranted. According to the Federal Highway Administration, there are 756 of the relatively unique steel deck truss bridges in the United States. Later in the investigation, the U.S. DOT cautioned states to carefully consider the additional weight placed on bridges during construction or repair projects. Though it has not yet indicated any definitive cause of the Minneapolis I-35W collapse, the National Transportation Safety Board (NTSB) has indicated that the stress on the gusset plates may have been a factor, and that one possible stress may be the weight of construction equipment and materials on the bridge. "Given the questions being raised by the NTSB, it is vital that states remain mindful of the extra weight construction projects place on bridges," Transportation Secretary Peters said. The I-35W bridge was opened in November 1967 and was 1607 feet in total length with a maximum span of 458 feet, about 64 feet above water. The bridge was unique because it was constructed with a single arch to avoid putting piers in the water which would impede river navigation.
