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.

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.
