Interstate 94 (I-94) runs east–west for through the southern half of the US state of North Dakota, from the Montana state line east to the Red River at Fargo. The route generally follows the route of the Northern Pacific Railway. Route description Eastbound, the route enters from Montana just west of Beach and passes Dickinson, Bismarck, Jamestown, Valley City, and West Fargo before entering Fargo, where it exits the state at the Red River of the North and continues into Minnesota at Moorhead, then turns southeast to Minneapolis. The route passes to the south of Theodore Roosevelt National Park's southern unit; access to the northern unit is by US Highway 85 (US 85) north from Belfield. Eastbound, I-94 changes timezones at the Stark–Morton county line southwest of Hebron. Mountain time (UTC−7) is observed in Stark County (and west) and Central time (UTC−6) in the rest of the state. The speed limit on I-94 is in rural areas. Between exits 152 and 159 in the Bismarck–Mandan area, the speed limit is . In the West Fargo–Fargo area, the speed limit is between exits 346 and 347, and from exit 347 to the Red River of the North. I-94 has two lanes in each direction through most of the state, expanding briefly to three lanes in each direction in the Bismarck–Mandan area (from exit 155 to 156) and in Fargo from 45th Street (exit 348) to the Red River of the North. The elevation of the highway at the Montana border is approximately above sea level, and approximately at its crossing of the north-flowing Red River, entering Minnesota at Moorhead. Points of interest The route enters at Beach and passes through the badlands near Medora and the south unit of Theodore Roosevelt National Park. A public rest area about east of Medora provides an awe-inspiring view, especially at sunset, and an opportunity to hike through some of the scenery on the Painted Canyon Trail. Further east, I-94 provides access to the north unit of the national park, then passes through the cities of Dickinson, Mandan–Bismarck, Jamestown, and Valley City on the way to West Fargo and Fargo, where it leaves the state and crosses into Minnesota. Through North Dakota, I-94 travels nearly due east–west, generally following both the railroad route and the former route of US 10 (called "The Old Red Trail" or "The National Parks Trail") to exit 343 in West
