Chicagoland traffic reports: GCM Congestion Map |
Chicago expressways
Expressway information is grouped according to travel direction through
the Chicago area from the Loop (downtown), or from the city limits if
a route does not originate in the Loop. This provides a general sense
of navigation, but it violates the laws of expressway numbering. For example,
I-90/94 is designated as an east-west route, but in Chicago it's actually
a due south route. Chicagoans usually speak of heading south on the Dan Ryan,
not "west".
