are recommended.
(a) Renumber present I-280 and the east-west section of I-74 as I-80.
(b) Renumber the east and north sections of I-80 as I-74.
(c) Renumber the north-south section of I-74 which is located through the urban area as either I-274 or I-280.
The above changes would also eliminate the present 9.4 mile overlap of I-74 and I-280 south of Moline.
Item #11 - Illinois - Chicago Area
There are several changes which the State desires to make in the numbering of Interstate routes in the Chicago area. A summary of these is as follows.
(a) Reroute I-90 over the Dan Ryan and John F. Kennedy Expressways and the northwest tollway.
(b) Reroute I-94 north on its existing location; then west along the proposed route of I-494 to join the Edens Expressway. This would delete route number I-494.
(c) Route I-290 from the Rohlwing Road interchange with the Northwest Tollway, south and east along the Eisenhower Expressway to its junction with I-90 (Dan Ryan Expressway).
It appears that the above changes would improve traffic operations in the area and eliminate several overlapping routes. Routes I-294 and I-80 are to remain unchanged. The above changes are recommended upon completion of the routes involved.
One additional item affecting the Chicago area is the routing of I-57. Within the last few years the State of Wisconsin has added an Interstate route from Milwaukee to Green Bay and selected I-57 as the route number. They also have requested Illinois to sign the route through Chicago to the Wisconsin line. This would result in overlapping of I-57 with other complicated routes in the Chicago area and also an overlap of I-94 from Chicago to Milwaukee. To alleviate this situation it is recommended that I-57 in Wisconsin be renumbered as I-39.
Item #12 - Missouri & Illinois - St. Louis - East St. Louis Area
