"Even-hundred" numbers indicate routes which branch off of the main highway, but return to it later. Thus, Interstate 290 in Chicago goes around the city, while I-90 goes downtown; they meet on both the southeast side and the northwest side. I-394 branches off I-94, heads due South, and terminates in a cornfield. Tom Roberts ihuxf!atlas1
