Travel directions

Highway 16 begins in Glendive, a small town off Interstate 94. The road then heads northeast through the cultivated valley of the Yellowstone River. The road passes several small villages and then reaches Sidney, a regional center near the border with North Dakota. There is a short double numbering with Highway 200, after which the road leaves the Yellowstone River valley and heads north across the steppe. This is a sparsely populated area, Highway 16 is often the only paved road. More than 50 kilometers to the north, you reach the Missouri River valley, where the US 2. exits at the village of Culbertsoncrosses. The road then continues north over the plains that have some minor elevation changes from badlands around Plentywood. After Plentywood, Highway 16 continues north for 25 kilometers to the border with Canada, then Highway 6 continues in Saskatchewan to Regina.

Highway 16 is one of Montana’s original state highways, although it originally ran only from Culbertson to the border with Canada. The part from Glendive to Sidney was numbered as Highway 14, in 1935 this was the only part of the route that was paved. On June 21, 1934, the bridge opened over the Missouri River at Culbertson, which was replaced by the current bridge in 1988. Around 1936-1937 the section between Culbertson and Plentywood was asphalted. Highway 16 became a gravel road in 1939extended from Culbertson to Sydney. This was paved around 1941-1942. By 1951, the northernmost portion of the route was paved between Plentywood and the Canadian border. In 1954, Highway 14 between Glendive and Sidney became part of Highway 16, creating the current route.

Highway 16 has primarily regional importance, despite being an international connection and connecting Highway 6 in Saskatchewan running directly to the capital, Regina. On the Saskatchewan side, however, a very sparsely populated area with hardly any villages follows the 150 kilometers before one uses Saskatchewan, so that the cross-border importance is limited.

Traffic intensities

3,000 to 4,500 vehicles drive daily between Glendive and Sidney, the busiest part of the route. From Sidney to Culbertson there are 1,600 to 2,500 vehicles and from Culbertson to Plentywood there are 1,000 vehicles per day. Farther north, 350 vehicles drive on the border with Canada.

Length 23 km

Highway 17 (MT-17) is a state route in the U.S. state of Montana. The road forms a short north-south route in the north of the state, from near Babb to the border with Canada, west of US 89. Highway 17 is 23 kilometers long.

Travel directions

North of the village of Babb, Highway 17 exits from US 89 and then heads northwest through a forested area along the base of the Rocky Mountains. In close proximity are mountains with peaks up to 2,800 meters, Highway 17 itself runs at 1,400 to 1,600 meters. To the north are the flat prairies. There is no place directly on the route of Highway 17, nor does it cross any other roads. After 23 kilometers you reach the border with Canada, after which Highway 6 in Alberta continues to Waterton.


The road was built around 1937 as an entirely new route to an alternative border crossing with Canada. The road was paved from the start and always connected to Highway 6 in Alberta. Compared to US 89 and certainly US 91 (later I-15), it is a secondary border crossing. The road mainly has a touristic character around the Glacier National Park.

Traffic intensities

350 vehicles use Highway 17 every day.

State Route 19 in Montana

Highway 19 (MT-19) is a state route in the U.S. state of Montana. The road forms a north-south route in the east of the state, between Roy and Grass Range. Highway 19 is 34 kilometers long.

Travel directions

Highway 19 begins at an intersection with US 191 east of the village of Roy. The road heads south, almost without curves, over flat rangeland. Highway 19 is the only paved road in the area. No place is directly on the route, but Highway 19 ends a short distance from Grass Range at US 87 and Highway 200.


Highway 19 originally ran from Lewistown to Malta, the function US 191 would later fulfill. In 1935 the entire road was unpaved. There was also a dirt road between Roy and Grass Range at that time. The current road was built as part of the new US 191 between Lewistown and Malta. Highway 19 thus became the connection from the south, US 191 from the southwest. Both routes were constructed as part of a series of roads around the new Fort Peck Lake. This reservoir was completed in 1940, but the roads were not built until much later. The current Highway 19 was also planned as Highway 19E for some time. The current road was completed as a paved road around 1962. A year later, the current road numbering of US 191 and Highway 19 was established.

Highway 19 has some importance for through traffic, it is part of the north-south link between Billings and Malta, linking Billings, the largest city in Montana, to the various small regional towns in the remote north of Montana.

Traffic intensities

Between 500 and 600 vehicles use Highway 19 every day. This is almost exclusively through traffic as there are no places on Highway 19.
