On December 15, 1967, bridge safety was thrust into the national spotlight. It was on this day that the Silver Bridge, an eyebar-link suspension bridge carrying Route 35 between Point Pleasant, West Virginia and Gallipolis, Ohio spanning the Ohio River, collapsed sending 47 people to their death. Measured by loss of life, this was the most horrific bridge failure in the United States. Congressional hearings concluded a few states and counties inspected some of their bridges, but there were no national standards to accomplish this task.
In 1968, Congress enacted the Federal Highway Act: US Code Title 23 Section 151 and as a result the National Bridge Inspection Standards (NBIS) were established. In 1971, the NBIS were mandated by Federal Law and were intended to ensure the proper inspection of the nation’s bridges greater than 20 feet in length on all public roads.
