The commission was instrumental not only in the early planning and development of the parkway but also in its construction, promotion, marketing, and development. Now known as the Mississippi River Parkway Commission and headquartered in Minneapolis, the commission continues to promote, preserve, and enhance the resources of the Mississippi River Valley and the Great River Road. Representatives of the 10 states and two Canadian provinces serve on the commission's board of directors, and they serve as chairpersons of their state Mississippi River Parkway commissions. But the road from the commission's beginning in 1938 to the success of the Great River Road today has been a long one—full of fits and starts. A late bloomer, the Great River Road was more than 30 years old before it really began to mature.
