North Dakota Highway 6 (ND 6) is a major north–south highway in North Dakota. It runs from South Dakota Highway 63 in McLaughlin to Interstate 94 Business Loop in downtown Mandan.

Route description

Highway 6 begins at the South Dakota-North Dakota State Line, and the northern terminus of South Dakota Highway 63. It intersects North Dakota Highway 24 twice, and in between the two ends of that road passes through Selfridge. North of there it passes by Breien, and later encounters the eastern terminus of North Dakota Highway 21 turning right at that intersection before making a sharp left curve and heading north again. At the intersection with Morton County Road 136 it passes by Saint Anthony, then runs along the west side of the Morton County State Game Management Area. A sign that the route is approaching its northern terminus is when it passes by the Mandan Municipal Airport. The route doesn't officially enter Mandan, until roughly around 19th Street, and from there it passes by a USDA lab, and a local Youth Corrections Center. It then crosses a bridge over the Heart River, where on the other side it becomes 10th Avenue and cuts through the Mandan Municipal Golf Course. Immediately after a bridge over the BNSF Mandan Rail Yard North Dakota Highway 6 ends at Interstate Business Loop 94, although 10th Avenue continues northbound as a local residential city street.
