Northern Missouri

Getting around rural Putnam County means state lettered routes and county gravel roads, and whether a road is county-maintained or private affects access, plowing, and upkeep.
Outside Unionville, getting around Putnam County means lettered state routes and a network of county gravel and dirt roads.
For a buyer, the practical question is whether the road reaching a property is county-maintained or private. That determines who grades it, plows it, repairs it, and whether year-round access is dependable.
A private or unmaintained road can make the owner responsible for upkeep. It can also change the feel of a place in mud season or after winter storms. Northern Missouri winters bring ice and blowing snow on top of the usual freeze-thaw, so a road that is fine in July can be hard in February.
Put road status beside the parcel map before buying rural land here. MoDOT covers the numbered and lettered routes; county or private maintenance is a separate question.
