Interstate 294 - Renumbering as I-94
Description This roadway will be renumbered as I-94 along its entire route. Instead of I-94 going into downtown Chicago the route will instead follow the Tri-State Tollway. See Midwest Interstate Renumbering for a map of all the planned route renumberings and more information.
Purpose and Need Promotes continuity of I-94 by allowing it to remain on the Tri-State tollway. Also promotes continuity within the greater interstate highway system.
The Illiana Toll Road - Ultimate Interstate 480
Description The Illiana Toll Road is a new toll corridor planned to connect I-65 to I-57 and I-55 south of the greater Chicagoland metro area. Initially this route was to continue east of I-65 and hook around to the north connecting to I-80/90 and I-94 near Michigan City. The highway was also at one time planned to connect to the southern end of I-355 at one point. However this route would be better served to connect to I-80 to the west instead. If the complete highway was built, including both the eastern and western extensions it would provide an excellent bypass for I-80 and as such should be numbered as I-480 but could also be numbered as either I-665, I-257 or I-455 instead.
Purpose and Need Promotes continuity of the interstate highway system and provides an additional bypass for truck traffic around Chicagoland.
