Project Budget

$ 5.3M

This comprehensive project spanned four miles of SR5/Overseas Hwy. in the Florida Keys, encompassing Whale Harbor and Windley Key, with a budget of $5.3 million. The project timeline stretched from May 2010 to June 2013.

Project goals

  • Improve emergency preparedness by reconstructing the northbound 10-foot shoulder to facilitate evacuation needs.
  • Enhance road safety by correcting cross-slopes for better water drainage and vehicle stability.
  • Promote sustainable transportation by adding dedicated bike lanes.
  • Increase roadway capacity through minor widening where feasible.
  • Improve drainage infrastructure to manage stormwater runoff effectively.
  • Ensure clear communication and transparency through public involvement strategies.
  • Minimize environmental impact by designing innovative drainage solutions to avoid wetland disruptions and accommodate a new sanitary sewer system.

Final outcome

  • A safer and more accessible roadway for residents, tourists, and emergency responders.
  • Improved drainage system for better flood control and road safety.
  • Dedicated bike lanes encouraging eco-friendly transportation options.
  • Enhanced capacity for managing traffic flow.
  • Successful public engagement and collaboration throughout the project.
  • Minimized environmental impact through innovative drainage design.

Challenges and Solutions: The project faced the significant challenge of managing extensive public involvement during construction. CWI effectively addressed this by implementing robust communication strategies and maintaining transparency throughout the process.
