A site-specific solution
Replacing the existing intersection with a roundabout led to improved traffic flow, access, and economic development.
Practices
Roundabout design solves access challenges for commercial development
West Knoxville’s original roadway grades and site constraints needed solutions that accommodated delivery vehicles and patrons. A roundabout design solved these challenges while providing necessary safety and access improvements, with construction costs coming in well under the initial estimate.
Extreme grade solutions
A new design accommodated delivery vehicles and customer traffic while working in the difficult corridor topography.
Economic development support
The roundabout rejuvenated West Knoxville, enabling successful commercial operations in a challenging location.
Under-budget delivery
Construction costs came in $50K less than the initial estimate, showcasing expertise in traffic engineering and sustainability.
The new roundabout provides safe access without sacrificing economic development potential for the community. Everyday drivers and destination drivers both realize the safety benefits and capacity improvements from the new traffic design. "This project showcases our talents in economic development, traffic engineering, roundabout design, sustainability, and roadway safety analysis," says project manager Chris Kirby. "At CDM Smith, we enjoy serving our community and it was rewarding to be part of a project that provides positive impacts in so many ways."
