Commercial and Industrial Network Improvement and Programming Policy, Summary, 1991

The Commercial and Industrial Network improvement and programming policy reflected in this summary report was adopted for use in future highway programming by the Transportation Commission on November 5, 1991. The Iowa Department of Transportation, as directed by the Legislature, has established a 2,331-mile network of commercial and industrial highways and is directing a significant amount of primary construction funding resources toward improvements to this network. This summary outlines the technical needs assessment for improvements on the Commercial and Industrial Network for the next 20-year period. The portions of the network which require four-lane capacity, as well as major improvements to the two-lane sections, are graphically displayed. Detailed improvement needs and costs are listed in tabular form for the first two five-year periods (1992-1996 and 1997-2001). It is essential to note that these improvement needs are the result of a technical assessment and do not imply any funding commitment.
