A brief summary was made of estimated needs on the 112,000 miles of roads and streets in Iowa in the 20-year period, 1960-1980. Basic recommendations for revision of system classification and for improved management and inter-governmental relations are also included. The report is based on engineering analysis of existing status of roads and streets compared to standards of design and maintenance required for future traffic. Projections of past trends to 1980 indicate: (1) A population gain of 400,000--all in cities--with a statewide total of 3,150,000 (2) A 40 percent rise in number of motor vehicles--reaching 1,800,000 (3) A 70 percent increase in total travel--reaching 20 billion vehicle miles annually. Some 63 percent of all travel is on rural and urban State Primary Highways, 19 percent on other urban streets, and 18 percent on secondary roads. (Author)
