With the completion of all the planning reports in early 1970, actual development of the Great River Road was ready to begin. Although a number of states put up Great River Road highway signs and used available state funds for scenic bluff protection and road improvements, full-scale development funds were not yet available. Legislation to fund the development of the Great River Road was included for the first time as part of the Federal-Aid Highway Act of 1973. From 1973 to 1982, Congress authorized a total of $314 million for the Great River Road. Most of those funds ($251 million) were allocated directly to the states.
