List of state highways in Montana
Wikimedia list article
The state highways in Montana are the state highways owned and maintained by the Montana Department of Transportation (MDT) in the US state of Montana.
Montana's state highways are classified as either primary or secondary. Several of Montana's state highways (both primary and secondary), or sections thereof, have also been designated as part of the National Highway System.
Primary state highways
The square markers used today to identify primary Montana highways are only slightly different from their 1940s and earlier predecessors. The old markers used the word "ROUTE" above the number in big size, the route number in the middle, and the word "MONTANA" from edge-to-edge at the sign bottom. The font used was similar to that used for US routes.
Special routes
Secondary state highways
Montana's secondary system was established in 1942, but secondary highways (S routes) were not signed until the 1960s. S route designations first appeared on the state highway map in 1960 and are abbreviated as "S-nnn". Route numbers 201 and higher are, with very few exceptions, exclusively reserved for S routes. Notable exceptions include, MT 287, and the former MT 789.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
