There are five business routes (two current and three former) in Montana for Hysham, Forsyth, Miles City, Glendive, and Wibaux.

The road continues in the same direction as it climbs a bridge over a former Northern Pacific Railway (NP) line, until it turns more to the east, running between the Range Riders Museum and the Miles City Fairground.

The route does not officially enter the city limits until it crosses a bridge over the Tongue River, and even then cuts between Riverside Park before running through the Main Street Historic District, which begins at Fourth Street and includes an intersection with Seventh Avenue where it encounters Montana Highway 59 (MT 59), and that route joins it in a concurrency.

flanks the east side of that former NP line and serves as the terminus of numerous local streets, except for Leighton Boulevard.

From there, the road passes by a truck weigh station next to a self-storage facility but continues to run relatively east mostly through local farmland.

Though signs on I-94 direct motorists to MT 200S, the road does not encounter that route until Alder Avenue in West Glendive, north of a parallel railroad crossing.

Dividing again at another bridge over Dry Creek, the route begins to curve to the east, and the road starts to run along the north side of some parkland, which also borders a former section of the road named Crisafulli Drive just before approaching the southern terminus of MT 16 and immediately crosses a railroad line on the border of West Glenside and Glendive.

Two blocks later at Clement Street, the historic district fades away within the vicinity of a former NP station now owned by BNSF Railway.

Some BNSF related buildings can be found north of there before the route passes by the chamber of commerce along the tracks, and later across from that, the grounds of Dawson County High School.

and MT 7 make a left turn onto Log Cabin Road and both routes end at exit 242 on I-94, which is another half diamond interchange that, in this case, has only a westbound offramp and eastbound onramp.

for Medora, North Dakota, runs from exits 24 to 27 on I-94 within Theodore Roosevelt National Park's South Unit.

After crossing a bridge over a tributary of that river named Andrew's Creek, it runs southeast as it follows the northeastern edge of a former NP line.

After the entrance to the Medora Camp Grounds, and the Chateau De Mores Visitor Center, I-94 Bus.

begins at a diamond interchange with 30th Avenue West and runs south-southeast then passes by housing developments built only within the 2010s as it curves toward the east approaching Villard Street (Old US 10, now Stark County Road 10 [CR 10]).

This segment runs northeast mainly passing car, truck, RV, farm equipment, and trailer dealerships and other local industries.

ends at another diamond interchange, specifically exit 64 on I-94, but 36th Street Southwest continues to run along the far north side of I-94.

[2] The route crosses a second bridge over the Heart River, where it officially enters Mandan and becomes West Main Street.

merges to run concurrently with ND 1806, which ends at 6th Avenue Southeast, and is also replaced by an overlap with the Lewis and Clark National Historic Trail.

At Mandan Avenue, the Lewis and Clark National Historic Trail turns north, and East Main Street heads to exit 155 on I-94, but I-94 Bus.

[3] On the east side of this bridge, Memorial Highway turns south across from the intersection with Frannie Barracks Road, and I-94 Bus.

The road curves slightly to the southeast then the northeast as it encounters another SOO spur west of Eastdale Avenue.

It curves to the northeast almost immediately after the intersection with CR 18 and the frontage road becomes a dead end just south of 4th Street West.

East of 5th Avenue West, I-94 Bus./US 10 Bus./US 52 Bus./CR 21 curves around the edge of the Sheyenne River, just south of the former NP station (now the "Rosebud Visitors Center"), then resumes its previous trajectory.

The overlap with CR 21 ends at Central Avenue, where that route turns north, and downtown Valley City begins to fade away at the intersection with 6th Avenue Northeast, where it passes a trailer park just before encountering the Sheyenne River again at the Rainbow Arch Bridge.

Joseph, Kalamazoo, Battle Creek, Marshall, Albion, Jackson, Ann Arbor and Port Huron to the freeway mainline.
