ST. CHARLES COUNTY – Drivers traveling on Route D near Route T may expect delays during a box culvert replacement project starting Monday, November 6. All work is weather permitting.
Crews will close Route D between Route T and Cappeln-Osage Road during construction. The signed detour will be Route T north to Route N east to Route Z south and vice versa. Route D is anticipated to reopen by February 2024.
The existing box culvert was built in 1936 and is in poor condition. Erosion is occurring on the Route D embankment due to frequent flooding during heavy rain events.
The project will replace the existing box culvert with a larger box culvert. The project also includes raising the elevation of Route D about 18 inches to reduce the frequency of roadway flooding.
