In the early afternoon, construction equipment and construction aggregates (sand and gravel for making concrete) were delivered and positioned in the two closed inside southbound lanes. The equipment and aggregates, which were being staged for a concrete pour of the southbound lanes that was to begin about 7:00 p.m., were positioned toward the south end of the center section of the deck truss portion of the bridge and were in place by about 2:30 p.m. About 6:05 p.m., a motion-activated surveillance video camera at the Lower St. Anthony Falls Lock and Dam, just west of the I-35W bridge, recorded a portion of the collapse sequence. The video showed the bridge center span separating from the rest of the bridge and falling into the river.

Point Pleasant's Silver Bridge, the first eyebar suspension bridge in the United States, was an engineering marvel when it was constructed in 1927 and 1928. Located on US Highway 35, the bridge spanned the Ohio River and linked Point Pleasant, West Virginia, with the towns of Kanauga and Gallipolis, Ohio. For almost 40 years, the structure provided dependable service for travelers in the region. On December 15, 1967, this service came to a dramatic and disastrous end. At 4:58 p.m., during the height of rush hour, the bridge suddenly collapsed. Rescue and recovery operations started immediately but were hampered by poor weather conditions and freezing rain. The cause of the collapse was linked to the bridge's innovative design. Undetected corrosion stress cracks caused an eyebar on the Ohio side to fracture; because the eyebars were linked together in a chain, the failure of one led to the catastrophic collapse of the entire bridge. In total, 46 lives were lost in the disaster.

As known, each bridge presents a unique set of design, construction, and maintenance challenges. The designer must determine the appropriate methods and level of refinement necessary to design and analyze each bridge on a case-by-case basis. The Innovative Bridge Design Handbook: Construction, Rehabilitation, and Maintenance encompasses the state of the art in bridge design, construction, maintenance, and safety assessment. Written by an international group of experts, this book provides innovative design approaches used in various parts of the world and explores concepts in design, construction, and maintenance that will reduce project costs and increase structural safety and durability. Furthermore, research and innovative solutions are described throughout chapters. The Innovative Bridge Design Handbook: Construction, Rehabilitation, and Maintenance brings together the specific knowledge of a bevy of experts and academics in bridge engineering in the areas of design, assessment, research, and construction. The handbook begins with an analysis of the history and development of bridge aesthetics and design; various types of loads including seismic and wind loads are then described, together with fatigue and fracture. Bridge design based on material such as reinforced concrete, prestressed reinforced concrete, steel and composite, timber, masonry bridges is analyzed and detailed according to international codes and standards. Then bridge design based on geometry, such as arch bridges, girders, cable stayed and suspension bridges, is illustrated. This is followed by a discussion of a number of special topics, including integral, movable, highway and railway bridges, together with seismic component devices, cables, orthotropic decks, foundations, and case studies. Finally, bridge construction equipment, bridge assessment retrofit and management, bridge monitoring, fiber-reinforced polymers to reinforce bridges, bridge collapse issues are covered. - Loads including seismic and wind loads, fatigue and fracture, local effects - Structural analysis including numerical methods (FEM), dynamics, risk and reliability, innovative structural typologies - Bridge design based on material type: RC and PRC, steel and composite, timber and masonry bridges - Bridge design based on geometry: arch bridges, girders, cable stayed and suspension bridges - Special topics: integral, movable, highway, railway bridges, seismic component devices, cables, orthotropic decks, foundations - Construction including construction case studies, construction equipment, bridge assessment, bridge management, retrofit and strengthening, monitoring procedures

Argues that failures in structural engineering are not necessarily due to the physical design of the structures, but instead a misunderstanding of how cultural and socioeconomic constraints would affect the structures.
