North Dakota Highway 31 (ND 31) is a 69.195-mile-long (111.359 km) state highway in the U.S. state of North Dakota. The route is split into two segments. The southern segment begins as a continuation of South Dakota Highway 65 (SD 65) at the South Dakota state line north of McIntosh and runs north to ND 21 southwest of Flasher. The northern segment begins at a diamond interchange with Interstate 94 (I-94) north of New Salem and runs north to Harmon Avenue in Stanton, where state maintenance ends and the roadway continues north as Mercer County Road 37 (CR 37).
The center line of ND 31 in Sioux County, in the Standing Rock Indian Reservation, serves as the boundary between the Central Time Zone to the east and the Mountain Time Zone to the west. [2]
Route description
Southern segment
ND 31 enters North Dakota at its southern border with South Dakota as a continuation of SD 65 just over one mile (1.6 km) north of its intersection with U.S. Route 12 (US 12) in McIntosh. From the state line, the route continues north as a two-lane road through the rolling prairies of Sioux County, all of which is located within the Standing Rock Indian Reservation. During ND 31's 10.35-mile-long (16.66 km) trek through Sioux County, its center line serves as the boundary between the Central Time Zone to the east and the Mountain Time Zone to the west.[2] At the northern end of this length, the roadway crosses Cedar Creek, at which point it enters Grant County, exits the Standing Rock Indian Reservation, and fully enters the Mountain Time Zone.
In Grant County, ND 31 continues north through hilly grasslands, crossing the Cannonball River about 2.5 miles (4.0 km) north of Cedar Creek. The road continues north for about 11 miles (18 km) before traversing the unincorporated community of St. Gertrude. North of here, ND 31 curves slightly to the northeast and travels 5.5 miles (8.9 km) more miles to Raleigh. One mile (1.6 km) north of Raleigh, the Grant–Morton county line intersects the roadway from the east and continues due north. For the next five miles (8.0 km), ND 31 travels either directly on or immediately adjacent to the county line, with Morton County to the east and Grant County to the west. This county line also serves as the boundary between the Central Time Zone to the east and the Mountain Time Zone to the west.[2] Finally, the southern segment of ND 31 ends at a T intersection with ND 21.
Northern segment
The northern segment of ND 31 begins at a diamond interchange with exit 127 of I-94 in Morton County, just north of New Salem. The roadway south of this interchange continues as 8th Street into New Salem; ND 31 travels north through mostly flat farm fields. About six miles (9.7 km) north of I-94, ND 31 crosses Sweetbriar Creek. It then passes east of a small wind farm before crossing into Oliver County about 2.3 miles (3.7 km) north of the creek.
In Oliver County, ND 31 continues due north through farm fields. Nine miles (14 km) north of the county line, the route enters unincorporated Hannover and intersects ND 25 at that route's western terminus. From here, ND 31 continues north as the surrounding terrain becomes hillier. Nine miles (14 km) north of Hannover, the route crosses into Mercer County.
ND 31 travels four miles (6.4 km) north through rural Mercer County before intersecting ND 200A. At this intersection, ND 31 turns east to join ND 200A, and the two routes run concurrent for just under two miles. Then, the road curves slightly southeast and reaches another T intersection at which ND 200A continues east toward Washburn and ND 31 turns northeast toward the Missouri River city of Stanton. The route crosses under the Zap Line railroad owned by BNSF, then curves north to parallel it as it enters the city. Within Stanton, ND 31 is known as West Street. It traverses the western edge of the city while running north to downtown, where it ends at an intersection with Harmon Avenue. North of ND 31's northern terminus, West Street continues as County Road 37 (CR 37).
