Local governments and businesses in central Illinois believe that a new highway connection between the metropolitan areas of Peoria and Chicago will shorten travel times and foster economic development. A geographic information system (GIS) that was used to determine the feasibility of alternative corridors being considered for an improved highway within the 10-county, 7,700-sq km (3,000 sq mi) study area is discussed. The development of the GIS required the compilation and integration of large amounts of geographic and environmental data. The data base was developed using a personal computer based GIS. Overlay analysis was used to map environmentally sensitive areas and possible engineering constraints. Previously developed corridor alternatives were entered into the GIS, and their locations and alignment designs were adjusted to avoid major engineering obstacles and environmental impacts. After the corridor locations were finalized, the GIS was used in the alternatives evaluation to assess the effects of the proposed corridors.
