| | 3-digit Interstates from I-35 |
 | | An early (1957-58) Iowa numbering plan had the numbers 235 and 380 overlapping along the entire route, perhaps to be fair to both I-35 and I-80. |
 | | Opened in 1989, Interstate 235 is named the Centennial Expressway for the 100th anniversary of the opening of the Unassigned Lands, better known as the Land Rush. |
 | | I-235, was shown as "proposed" since the 1970s, but never appeared on state maps until the late 80s. |
