Supporting Economic Growth: The new interchange provided critical infrastructure to support Toyota's expansion, including the addition of Lexus vehicle production, while enhancing regional economic development.

Improving Regional Mobility: The project created a new interstate access point that relieved congestion along the US-62 corridor and improved access for employees, freight, and the surrounding community.

Innovative Traffic Solutions: The use of VISSIM traffic simulations allowed the team to evaluate multiple intersection alternatives and implement the most efficient long-term solution.

High Traffic Demand: The roundabouts were required to accommodate more than 2,000 vehicles exiting the Toyota facility within a 30-minute shift change while maintaining safe and efficient operations.

Complex Vehicle Mix: The design needed to safely serve both high volumes of passenger vehicles and large delivery trucks without compromising traffic flow or safety.

Long-Term Performance: The project required a solution that improved operational efficiency while reducing maintenance needs and supporting future growth at the facility.

Improved Traffic Flow: Dual-lane roundabouts replaced signalized intersections, significantly reducing traffic queues and travel times compared to preconstruction conditions.

Enhanced Safety: The completed roundabouts reduced crashes while providing safer, more predictable traffic operations for employees and freight traffic.

Proven Design: Since opening in 2016, the roundabouts have successfully met operational goals and are being studied as a model for similar high-volume intersections at other locations.
