MapQuest Illinois: Where the Illinois trip sits
Use MapQuest Illinois to read Illinois as a set of destinations rather than one pin. Chicago, Springfield, Rockford sit in different planning contexts, and the final address should decide the route. Illinois planning changes substantially between the Chicago region and downstate corridors, so traffic, tolls, and destination type should be specified early.
Read the geographic overview of Illinois before treating I-55, I-57, and I-90/I-94 as a complete itinerary.
Where the Illinois trip sits
Illinois is known as the Prairie State, but the map works better when that identity is translated into I-55, I-57, and I-90/I-94 and a complete destination address.
Use the capital as a reference
The planning decision in Illinois is regional before it is local. Springfield and Chicago are useful anchors, but I-55, I-57, and I-90/I-94 only becomes meaningful after the endpoint is known.
A local search in Illinois should preserve the distinction between Chicago, Springfield, and Rockford. Each named place can shift the relevant part of the I-55, I-57, and I-90/I-94 network.

MapQuest Illinois is most useful for Illinois after the corridor is narrowed to I-55, I-57, and I-90/I-94. From there, verify whether the route ends near Chicago, Springfield, or another named destination.
