Interstate 29
Interstate Highway in the Midwestern United States
Interstate 29 (I-29) is an Interstate Highway in the Midwestern United States. I-29 runs from Kansas City, Missouri, at a junction with I-35 and I-70, to the Canada–United States border near Pembina, North Dakota, where it connects with Manitoba Provincial Trunk Highway 75 (PTH 75), which continues on to Winnipeg, Manitoba. The road follows the course of three major rivers, all of which form the borders of US states. The southern portion of I-29 closely parallels the Missouri River from Kansas City northward to Sioux City, Iowa, where it crosses and then parallels the Big Sioux River. For the northern third of the highway, it closely follows the Red River of the North. The major cities that I-29 connects to includes (from south to north) St. Joseph, Missouri; Council Bluffs, Iowa; Sioux City, Iowa; Sioux Falls, South Dakota; Fargo, North Dakota; and Grand Forks, North Dakota. I-29 also serves as a road connection between the four largest public universities in the Dakotas: the University of North Dakota, North Dakota State University, the University of South Dakota, and South Dakota State University.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
