IL ROUTE 159 FEASIBILITY STUDY
CONSTRUCTION COST: $150,000 (study)
COMPLETION DATE: 2004
CLIENT: CITY OF COLLINSVILLE

The Illinois Department of Transportation is in the process of improving IL-159 to the north and south of Collinsville. After this construction, IL-159 will be five-lanes wide from Fairview Heights to just north of Morrison Street, and from the Belt Line to Edwardsville. This will leave about a two-mile segment through Collinsville at two- or three-lanes wide, creating a potential traffic bottleneck.

This study investigated the potential for either improving or supplementing IL-159 between the two five-lane segments. Within the nine square mile study area, six alternate routes were evaluated to supplement the existing Route 159. Study goals and objectives included improving traffic flow, supporting the City's comprehensive plan and economic development, and preserving historical, cultural and environmental resources.

The study examined current and future traffic demands, land use and social, economic and environmental impacts for the identified alternates. Construction cost estimates were also prepared for each of the alternates.

This study required significant public involvement activities, including several public meetings and presentations to local interest groups, preparation of press releases and presentations to the City Council.
