The Eastern Bypass Study is part of a long-range planning project taken on by the Illinois Department of Transportation (IDOT). The study is currently determining the best corridor location to improve travel flows and the development of communities in the region. Various routes have been explored and there are currently four broad (3,000 foot wide) paths moving ahead. The next phase of the Eastern Bypass Study will be an alignment study where more detailed information is gathered in order to develop various highway alignment alternatives within the selected corridor(s).

TERRA provides GIS and Public Involvement services for the project. A Community Advisory Group (CAG) consisting of 47 individuals representing regulatory agencies, local municipalities, interest groups, and local stakeholders was selected. Guided by facilitators, the CAG discusses topics relating to the Eastern Bypass Study and helps direct the study team regarding local issues and preferences. The CAG’s role is to reach a consensus regarding different topics and recommend which corridors to keep in the study or to drop from consideration. The Eastern Bypass Study has been designated a Context Sensitive Solutions (CSS) project by IDOT. TERRA’s public involvement specialists work with the CAG and the general public to ensure their insights and concerns are considered and addressed throughout the planning process.

GIS Analysis was conducted on many different layers to help identify and quantify environmental and community impacts. Hard copy maps and Google Earth files have been delivered to various stakeholders throughout the project’s history. To learn more about the Eastern Bypass, please visit the Eastern Bypass website.
