Lying in the center of North Dakota, just a short distance north of Fort Lincoln (where General Custer began his fateful journey to the Little Bighorn), the historic city of Mandan has preserved its, Old West legacy, in part, through an extensive renovation of Fort Lincoln. Situated at the intersection of Interstate 94 and the Missouri River, Mandan is also known as a railroad town. Indeed, the town has one of Burlington Northern's major switching yards located in the heart of the city. The confluence of these railroad tracks and the traffic between Fort Lincoln and Mandan has brought about the construction of he first prestressed concrete railroad bridge in North Dakota.
