The north end of this tollway was the south end of an existing freeway numbered IL-53. There are plans to extend this route both north and south from the existing route. In 1990 it was changed another time, this time to I-88. This was due to the federal speed laws that then only allowed 65 MPH on Interstates. The last few miles from Hazelcrest to the Bishop Ford it is also I-80.
Several ramps collect tolls as well.
I-94 follows the Spur. 29 Touhy Av. The route has I-90 on its entire length. Several ramps on or off the road also collect tolls. Oasis's are at Des Plaines and Belvidere.
