The Federal Aid Highway Act of 1968 required the Secretary of Transportation to establish a national bridge inspection standard and to develop a program to train bridge inspectors. During the 1970s many steps were taken to ensure proper inspection and maintenance of in-service bridges, including the creation of the National Bridge Inspection Standards (NBIS) in 1971 along with implementation manuals. Supplements to the Federal Highway Administration's Bridge Inspector's Training Manual were issued during the 1980s. The concept of hands-on inspection came about as inspectors realized that a thorough inspection of a bridge required getting close enough to the bridge member or component so that it can be touched with the hands. Also, special inspection access equipment and vehicles were developed, along with specialized training in their operation and maintenance.
