The portion of I-290 from I-294 to its east end is officially called the Dwight D. Eisenhower Expressway. In short form, it is known as "the Ike" or the Eisenhower. Before being designated the Eisenhower Expressway, the highway was called the Congress Expressway because of the surface street that was located approximately in its path and onto which I-290 runs at its eastern terminus in the Chicago Loop.
