1 Illiana Corridor PHASE I STUDY Stakeholder Alternatives Summary October 25, 2011

2 Alternative Development Summary Potential irst Round Major Corridors Stakeholder Suggested Alternatives Potential Conceptual Alternatives Stakeholders Identify Concepts igure 2 igure 4 Additional Links to Initial Alternatives igure 1 igure 3 Identify Concepts: alternatives were developed from Summary of Modes Submitted the stakeholder suggestions. All of those alignments can be seen in igure 1. Many different types of improvements were suggested, including freeway alternatives, arterial improvements, and rail only options. Corridor alignments, shown in igure 2, include a buffer around alternatives with similar locations. points, avoiding densely populated areas, and other identified constraints. > 35 included a tolling option > 19 included General Purpose highway lanes > 21 included a freight rail component These potential conceptual alternatives were then further refined to avoid > 23 included a Public Transit component natural features, environmental constraints and other large impacts igure 3 > 11 Arterial Alternatives depicts these 21 groupings. The alignments will be screened using a 400 buffer for direct environmental impacts and a 2000 buffer for inventory of items adjacent to the potential corridor. > 16 included P3 Alignments were then grouped together based on similar starting and ending igure 5 rom those 21 alignments, 8 primary corridors emerged, which encompass a majority of the alternatives (as shown in igure 4), with slight variations presented as possible links to the major corridors. Travel benefits will be the same for corridors in similar locations, so less impacting corridors were designated as the primary routes to evaluate in this round. igure 5 displays the additional links to the 8 primary corridors.
