In an effort to alleviate traffic at a busy intersection in Nashville, KCI worked closely with the Metropolitan Government of Nashville and Davidson County (Metro) to implement a cost-effective traffic solution.

For years, discussions had been in the works between city officials and the surrounding neighborhood to replace the four-way stop at Sawyer Brown Road and Todd Preis Drive with a traditional-sized roundabout. While this solution would help curb speeding and prevent traffic congestion, the high cost and potential property acquisition that would be required prevented the project from moving forward.

Instead, our team suggested that Metro consider building a mini roundabout. This design solution would provide the neighborhood with the same benefits of a traditional roundabout, but within a smaller footprint. By fitting the traffic circle within the existing space, Metro didn’t have to worry about right-of-way issues and was able to reduce costs by eliminating the need for utility relocations, storm sewer work and new curb alignments. Additional cost savings were achieved through the condensed design and construction schedule, which called for the entire intersection to be completed in six months. With construction now complete, vehicles are now able to safely make their way through the area with minimum traffic delays.
