MODOT is planning on having a busy summer in Oregon County, Missouri. One of the construction projects they’re working on is Highway M, which will be worked on from March through October.
Construction
MODOT will be replacing culverts, repairing pavement, and performing bridge maintenance throughout those months.
Time
The construction is planned to start on March 16, 2026, and will end on October 30, 2026. Each day, construction workers will be out from 6:00 am to 6:00 pm daily, weather permitting.
One Lane
Due to the construction happening, Highway M will be reduced to one lane with a 10-foot wide restriction. [1]
