New Box Culvert on Hwy D

On February 14, Route D between Route T and Cappeln-Osage Rd opened as scheduled by MoDOT. The closure was in place during the construction of a new box culvert.

Work began in early November 2023 to replace the existing box culvert, built in 1936 and in poor condition. Erosion occurred on the Route D embankment due to frequent flooding during heavy rain. The project replaced the existing box culvert with a larger box culvert. The project also included raising the grade of Route D about 18” to reduce the frequency of roadway flooding.
