Editing Interstate 29 (section)

===Interstate 31===
The portion from [[Fargo, North Dakota]], to the Canada–US border was originally considered for designation as '''Interstate&nbsp;31''' ('''I-31''') in 1957 for present-day I-29.<ref name=plan1>[[:File:Interstate Highway plan August 14, 1957.jpg|Official Route Numbering for the National System of Interstate and Defense Highways]], August 14, 1957</ref> No freeway was initially planned south of Fargo. However, it was subsequently decided in 1958 to connect I-29 and I-31 between Sioux Falls and Fargo. The entire freeway was then built and numbered as I-29.<ref name=plan2>[[:Image:Interstate Highway plan June 27, 1958.jpg|Official Route Numbering for the National System of Interstate and Defense Highways]], June 27, 1958</ref>
