Clay County gravel roads get different winter treatment
Clay County says gravel roads are not treated with salt and sand, so rural winter driving needs a different check than city streets or state highways.
Clay County winter driving is not the same on every road. Road and Bridge handles county-maintained roads and streets in unincorporated Clay County. MoDOT handles Missouri numbered or lettered routes, U.S. highways, and interstates. City streets belong with the city.
The gravel-road detail is the one a newcomer can miss. Clay County does not use salt and sand on gravel roads because they can damage the road; slick gravel roads are plowed or maintained with a motor grader instead.
That is not a warning to avoid rural Clay County. It is a calm winter-weather check. Use MoDOT for state highways, the city for city streets, and Clay County Road and Bridge for county-maintained rural roads, especially after ice when a gravel lane may not behave like pavement.
