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:
- Aesthetics: bridge, roadway, retaining
walls, lighting, scenic qualities
- Biological Resources: reforestation,
prairie mitigation, wildlife considerations
- Natural resources: surface and
groundwater, karst geology, erosion control
- 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.
