Why is the Chicago Skyway no longer I-90?
Actually, according to FHWA, it still is. In late 1999, Chicago added a TO banner to all the I-90 reassurance markers on the city-maintained Skyway ( http://www.chicagoskyway.org/ ). Apparently the city was looking at old records and realized it was never technically approved as an interstate (see http://groups.google.com/group/misc.transport.road/msg/2044938ffca6c8b4 , message ID n9jig-2008991217310001@chi-pm4-1a-40.theramp.net ).
