ACEC kansas awards

We are excited to share two Affinis clients have received Engineering Excellence awards for recent improvements. The City of De Soto, Kansas and the City of Leavenworth, Kansas were both recognized by the American Council of Engineering Companies (ACEC) Kansas. Below, you’ll find more about each of the winning projects we completed together.

City of De Soto, Kansas: 91st and Lexington Roundabout
The intersection at 91st Street and Lexington Avenue is located near De Soto High School and a few commercial businesses. The area has significant traffic with K-10 highway nearby. During peak hours, it was a challenge for drivers to make a left-hand turn from 91st Street, and some were taking unnecessary risks. The City of De Soto, Kansas was looking for the best solution.

The intersection did not meet the engineering criteria needed to install a new traffic signal. Consequently, the City of De Soto began extensively studying the intersection. A 2012 study suggested that installing a roundabout would improve traffic flow and safety. Affinis was selected for the design in June 2020. Learn more about the project here.

City of Leavenworth, KS: Thornton Street, from 10th Street to 5th Avenue
The City of Leavenworth, Kansas regularly conducts a city-wide pavement analysis to rate each street and identify which improvements are most pressing. Thornton Street had been on the city’s radar for years. An east/west collector, the existing two-lane asphalt roadway, curb, and sidewalk were in poor condition. The repairs needed went beyond simple maintenance.

The city retained Affinis to perform a concept study to determine the roadway typical section, roadway geometrics, and project costs. The study recommended reconstructing Thornton to a two to three-lane asphalt pavement section with concrete curb and gutter and a 5-foot sidewalk constructed on both sides of the street, as the most cost-effective solution to meet the city’s design criteria. Once selected, Affinis worked with the city to take a comprehensive approach to make other needed improvements to extend the infrastructure’s life. Learn more about the project here.
