There are five business routes (one former) wholly in North Dakota with a sixth that crosses into Minnesota. They connect to
Medora,
Dickinson,
Mandan–
Bismarck,
Jamestown (former),
Valley City in North Dakota and the cities of
West Fargo,
Fargo and
Moorhead, Minnesota.
Medora business loop Interstate 94 Business (
I-94 Bus.) for
Medora, North Dakota, runs from exits 24 to 27 on
I-94 within
Theodore Roosevelt National Park's South Unit. Named "Pacific Avenue", I-94 Bus. is the main road through Medora. I-94 Bus. begins at a quarter
cloverleaf interchange with I-94 on the southwest banks of the
Little Missouri River. 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. Simultaneously, the "Maah Daah Hey Trail" runs along the opposite side of the road. After the entrance to the Medora Camp Grounds, and the Chateau De Mores Visitor Center, I-94 Bus. crosses its own bridge over the Little Missouri River and enters "downtown" Medora. Various
Western-themed structures and tourist attractions can be found within the community. East of 6th Street, I-94 Bus./Pacific Avenue begins to curve away from the railroad line toward the northeast. I-94 Bus. ends at a flyover ramp on I-94 (exit 27), but only for eastbound traffic reentering the Interstate and westbound traffic leaving the Interstate.
Dickinson business loop Interstate 94 Business (
I-94 Bus.) for
Dickinson, North Dakota, runs from exits 59 to 64 on I-94. It consists of 30th Avenue West, Villard Street, and 36th Street Southwest. I-94 Bus. begins at a diamond interchange with 30th Avenue West (I-94 exit 59) 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]). Almost immediately after the route moves onto Villard Street, it approaches a signalized intersection with State Avenue, which is North Dakota Highway 22 Truck (ND 22 Truck) south. I-94 Bus. soon reaches the next signalized intersection,
ND 22 (3rd Avenue West) itself. At the next signalized intersection with 10th Avenue East, I-94 Bus. leaves Villard Street and shifts onto 36th Street Southwest, which is signed as "I-94 Business" along street name signs. This segment runs northeast mainly passing car, truck, RV, farm equipment, and trailer dealerships and other local industries. I-94 Bus. ends at another diamond interchange, specifically exit 64 on I-94, but 36th Street Southwest (old US 10) continues to run along the far north side of I-94.
Mandan–Bismarck business loop Interstate 94 Business (
I-94 Bus.) for both
Mandan and
Bismarck, North Dakota, runs from exit 147 west of Mandan to exit 161 in Bismarck. The route begins at exit 147, a diamond interchange with
ND 25 in Mandan and runs south from that interchange to an intersection with Morton CR 139 (formerly US 10), where it turns southeast. Continuing over the hills of North Dakota, it approaches the north side of a former
NP line now owned by
BNSF Railway, and both the road and railway cross bridges over the
Heart River, as the eventually enter the unincorporated community of Sunny. The route crosses a second bridge over the Heart River, where it officially enters Mandan and becomes West Main Street. The first signalized intersection in the city is with the northern terminus of
ND 6 at the intersection with 10th Avenue Northwest. West Main Street becomes East Main Street at Collins Avenue. Starting at 6th Avenue Southeast, it has a concurrency with
ND 1806 and is also replaced by an overlap with the
Lewis and Clark National Historic Trail. At Mandan Avenue, ND 1806 and the Lewis and Clark National Historic Trail turns north, and East Main Street heads to exit 155 on I-94, but I-94 Bus. turns southeast again onto Memorial Highway, crossing under and then running along the south side of that same former NP line. The line curves east away from the road just before the intersection with 32nd Avenue Southeast across from that, then I-94 Bus. curves to the east as it approaches an unorthodox interchange with
I-194 (Bismarck Expressway) before it crosses the new
Liberty Memorial Bridge over the
Missouri River to enter
Bismarck. On the east side of this bridge, Memorial Highway turns south across from the intersection with Frannie Barracks Road, and I-94 Bus. smoothly moves onto West Main Avenue. After a pedestrian bridge, the route encounter a bridge for the same former NP line just before an at-grade interchange with West Rosser Avenue and turns southeast as it runs along the north side of those tracks once again. The road and the tracks turn east again at Washington Street. At North 1st Street, West 1st Avenue becomes East 1st Avenue across from Camp Hancock State Historic Site Further in town, the road continues not only to run along that old NP line but even the beginning of a former
Soo Line Railroad (SOO) line, now owned by
Canadian Pacific Railway. That line has a spur leading to a grade crossing between East 24th and 26th streets. At 7th Street, it meets southbound
ND 1804 (one way). At 9th Street, it meets northbound ND 1804 (one way). The road curves slightly to the southeast then the northeast as it encounters another SOO spur west of Eastdale Avenue. The northeastward curve of the road almost ends just before I-94 Bus. turns north onto the "East
Bismarck Expressway". I-94 Bus. ends at exit 161, another diamond interchange on I-94/
US 83, then turns into a local street named Centennial Road.
Former Jamestown business loop {{infobox road small
Interstate 94 Business (
I-94 Bus.) was a former business loop of I-94 that existed within
Jamestown between exits 257 and 260. It consisted of 17th Street Southwest,
US 281,
US 52, 10th Street Southeast, 12th Avenue Southeast, and Business Loop East until it was decommissioned on April 7, 2004.
Valley City business loop Interstate 94 Business (
I-94 Bus.) for
Valley City runs from exits 290 to 294 on I-94/US 52. It is also concurrent with
US 10 Bus. and
US 52 Bus. The route begins at exit 290, a half diamond/quarter cloverleaf interchange. More specifically, its the eastbound lanes have half the diamond interchange onto CR 19 (24th Avenue Southwest), while the westbound lanes contain an elongated right-in/right-out ramps onto Main Street west of the bridge over CR 19. The two segments of I-94 Bus. intersect with one another and run eastbound along Main Street, which contains a flanking frontage road along the south side. 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. From 9th Avenue West to 7th Avenue West, Main Street curves back to straight east again, but, in between at 8th Avenue, the routes are joined by another overlap, specifically with CR 21. 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. East of the bridge, the surroundings are less urban, but not entirely undeveloped, until the road curves to the southeast. Just after the intersection with 7th Street Southeast and "Old US 10", I-94 Bus./US 10 Bus./US 52 Bus. ends at exit 294, a diamond interchange that replaced a former
Y interchange located east of the former NP and
SOO bridges on I-94 east of the current interchange.
West Fargo-Fargo–Moorhead business loop Interstate 94 Business (
I-94 Bus.) for
West Fargo, North Dakota,
Fargo, North Dakota, and
Moorhead, Minnesota, is the only I-94 business route that runs between two states. It begins at exit 343 on
I-94/
US 52 in
Mapleton Township, and runs on Main Avenue through
West Fargo and
Fargo. Upon crossing the
Red River of the North into
Moorhead, Minnesota, I-94 Bus. continues on Main Avenue until reaching 24th Avenue South, at which point it turns east over to 34th Street South. The route then turns south and ends at exit 2B on
I-94/
US 52 in Moorhead, Minnesota. The route is concurrent with
US 10 in both states, but, in Moorhead, US 10 makes a left turn at
US 75 for one block north. ==Michigan==
