Glacier Shadow Pass - Key Design and
Environmental Issues

• IDOT is committed to working collaboratively with
  all involved stakeholders via the Context
  Sensitive Solutions (CSS) process to address
  sensitive issues
• Corridor-wide lighting, wildlife crossings,
  aesthetic issues, environmental impact mitigation
  (wetlands, Karst features, native prairie,
  threatened/endangered species)
• Tapley Woods alignment and cross section
• Eagle Ridge noise and environmental impacts

US 20 Study Findings Support Improvement Needs

• Lack of proximate high-capacity routes
• 50 miles to I-88 100 miles to I-90
• Current and predicted future traffic volumes
  support need for 4-lane freeway
• Over 50 of roadway has substandard design
  features
• High crash frequency and severe crash types
• 1984 to 2002 3,943 crashes resulting in 1,701
  injuries and 58 fatalities
• 2003 to 2006 711 crashes resulting in 226
  injuries and 8 fatalities

US 20 Proposal Yields Near and Long Term Benefits

• Construction-related economic benefits
• supports over 20,000 construction-related jobs
• Long term transportation and economic benefits
• high-type east-west corridor providing reliable
  travel between Illinois, Iowa and Wisconsin
• roadway design compatible with current standards
  will improve safety
• improved transportation connectivity will support
  statewide and local economic development
  objectives

24
Local Support is Vital to Enable Project
Implementation

• Local coalition with consensus position
• Political leadership
• Active participation in future project
  development activities
