91st & Lexington Roundabout

De Soto's 5-Year Capital Improvements Plan allocates $1.25 Million for a 2-lane roundabout at the intersection of 91st and Lexington Avenue. Construction is scheduled for the summer of 2021. The project will be partly funded by a $455,000 allocation from the Johnson County CARS Program.

RoundaboutThe project is needed to alleviate a significant congestion problem that occurs when school traffic is at its peak in the mornings and afternoons on school days. After consideration of numerous alternatives, a roundabout was selected as the only solution that will solve the congestion problem without causing other, more serious issues. This conclusion was based on recommendations from several traffic studies conducted over the past 18 years which recommend against the installation of a traffic signal.

The most recent study, conducted in 2018, recommends a roundabout as the most effective solution to address the current congestion issue and also fully account for future additional traffic. As part of the study, the consultant produced a series of videos that depict live-action renderings of the function of a roundabout at the intersection. These videos are available here: https://drive.google.com/open?id=1r9l2DMTkbCQcp_nF-kAwEXGD6SqRc3zW.  

In June of 2020 De Soto hired Affinis Corporation to perform the engineering design for the project. 

A virtual public meeting was held on July 29th, 2020. The video from that meeting is available at the link below.
