What is the main highway route that runs through North Dakota?

The main highway route that runs through North Dakota is Interstate 94. This highway is significant because it serves as a crucial east-west corridor, connecting various cities throughout the state, including Fargo and Bismarck, and linking North Dakota to other major interstate systems in the United States. Interstate 94 facilitates not only local travel but also interstate commerce, making it an essential route for transportation in and out of the state.

Other numbered routes such as U.S. Route 1 and U.S. Route 2 do pass through parts of North Dakota, but they do not serve as the principal highway running across the entire state. Similarly, Interstate 90 primarily runs through other states, such as South Dakota, and does not directly traverse North Dakota, making Interstate 94 the most prominent and vital highway within the state.
