Montana Highway 200 (MT 200) in the U.S. state of Montana is a route running east-west covering the entire state of Montana. From the starting point at ID 200, near Heron, Montana the highway runs east to ND 200 near Fairview, Montana. It is part of a chain of state highways numbered 200 which extend from Idaho across Montana, North Dakota and Minnesota. Montana Highway 200 is also the longest route signed as a state highway in the United States.
The highway runs parallel to the Blackfoot River from McNamara to Milltown. The highway is subject to hazardous driving conditions in the winter, particularly due to black ice. The road crosses Rogers Pass on the continental divide on its way west to Missoula.
At its western end, west of Missoula, Highway 200 follows the Clark Fork River eastward at the feet of the Cabinet Mountains until it meets the Flathead River at MT 135. It then follows the Flathead River east to Dixon where the Flathead River turns north. Highway 200 continues east following the Jocko River until it intersects with US 93 at Ravalli. The highway then bends south to join I-90 going east into Missoula.
Today's Highway 200 is part of a four-state chain of such routes, but it did not begin that way. It was assembled from other state and federal routes over the years.
The status of the routes and route segments that became Highway 200 in 1937.
- The section from the Idaho line to Ravalli was the original MT 3.
- No concurrency from Ravalli to Missoula on US 93 or US 10.
- The section from Bonner to Sun River was then MT 20, and much was yet to be constructed. The route even followed segments of today's MT 21 to Augusta and future US 287 (then MT 33).
- No concurrency from Sun River to Grass Range along US 87.
- The section from Grass Range to Circle was part of the original MT 18.
- The remainder of MT 18 ran from Circle to Glendive, today's MT 200S.
- The section from Circle to Sidney was Montana 23, ending at then MT 14.
- MT 14 ran the rest of the way to Fairview.
Between 1948 and 1959, many construction projects and route redesignations with concurrencies made MT 20 from Bonner to Sidney the baseline for today's MT 200. MT 23N replaced MT 14 from Sidney to Fairview and MT 20S replaced MT 18 from Circle to Glendive.
In 1960, MT 20 picked up the Sidney to Fairview segment.
By 1969, the entire MT 20 had become MT 200 and included the former US 10A from Idaho to Wye, and following US 10 and 93 through Missoula. MT 20S became 200S.
