Public Meeting Information: Feb. 10, 2026

A public meeting was held Tuesday, Feb. 10 to discuss improving the intersection of U.S. Route 61 and Route 80 near Matthews, Missouri. During the meeting, MoDOT shared two alternatives for this safety improvement project—installing traffic signals or constructing a roundabout. The meeting materials (below) include an overview of potential right-of way impacts, cost, and the safety and traffic performance of each alternative. 

Tentatively, construction could begin as early as June 2027. Once work begins, it will be underway for approximately nine months. Motorists should anticipate delays, but the intersection will remain open to traffic during construction.
