  Project Scope
  The scope of the Galena Bypass project includes the design of a fully access controlled, four-lane freeway for a distance of approximately 6.5 miles. Interchanges will be provided at IL 84, northwest of Galena, and at existing US 20, near Horseshoe Mound. The proposed alignment includes 8 new bridge structures and improvements along 6 crossing and adjacent roadways.

The initial task of the Phase II design process was to refine the profile (elevation) of the proposed freeway in order to minimize adverse impacts to the surrounding areas, address environmental concerns and enhance visual aesthetics of the freeway. A geotechnical investigation of the subsurface conditions along the project route identified possible karst features (sinkholes, fractured bedrock, caves, mines, etc.) and weak soil zones that may be susceptible to sliding and subsidence. The data from this  investigation will be used to design the proposed roadway for stability, longevity and serviceability, and to minimize adverse impacts to the environment including groundwater contamination.

The Illinois Department of Transportation is committed to continue public involvement activities through the Phase II engineering process and construction of the Galena Bypass in a similar fashion as the Glacier Shadow Pass Study. The Department assisted in the formation of a Phase II Citizens Advisory Group to ensure that negative impacts of the project are minimized and to provide an opportunity for local review and coordination throughout the design process.

Issues of public interest included the following:
  1. Aesthetics: bridge, roadway, retaining walls, lighting, scenic qualities
  2. Biological Resources: reforestation, prairie mitigation, wildlife considerations
  3. Natural resources: surface and groundwater, karst geology, erosion control
  4. Construction Impacts: noise, air quality, construction waste, emergency vehicle access.

The purpose of the Citizens Advisory Group is to allow opportunity for public input on various aesthetic issues and to ensure compliance with Project Commitments made during the development of the Environmental Impact Statement.

In addition, The Phase II engineering design work will be presented to the community during at least two Public Informational Meetings offered during the design process. Comments from these meetings, input from the Citizens Advisory Group and coordination with local agencies will be taken in to consideration to refine the design and develop a cost effective transportation solution that fits into its surroundings – a Context Sensitive Solution.
