Illinois Route 59 is a north–south state highway serving the western suburbs of Chicago, traversing Will County, Kane County, and Cook County. The route connects suburban nodes such as Plainfield, Naperville, Aurora, North Aurora, St. Charles, Bartlett, and Elgin, providing links to major corridors including I-55, I-88, I-355, and U.S. Route 20.
Route description
Illinois Route 59 begins at a junction with I-55 near Plainfield and proceeds north as a multi-lane arterial through rapidly developing suburbs, intersecting commercial centers near Naperville and passing the Dupage Airport-area suburbs toward Aurora. The route provides direct access to shopping districts adjacent to Fox River Mall and commuter hubs served by Metra lines including the BNSF Railway corridor and the Union Pacific West Line. Crossing the Fox River region, it links historic downtowns such as St. Charles and connects with expressways like I-88 and I-90 via nearby interchanges. In northern Cook County, the corridor threads through Schaumburg-adjacent retail zones and terminates at U.S. Route 20 in Elgin, interfacing with transit nodes serving O'Hare International Airport and regional freight routes like the Canadian National Railway.
History
The corridor that became Illinois Route 59 developed from 19th-century plank roads and stagecoach alignments linking Chicago with westward settlements such as Aurora and Elgin. State designation occurred in the early 20th century amid statewide road-building initiatives led by figures associated with the Good Roads Movement and agencies analogous to the later Illinois Department of Transportation. Postwar suburbanization driven by projects like Interstate Highway System construction and demographic shifts to suburbs such as Naperville and Plainfield transformed Route 59 from a rural connector into a commercial arterial. Major reconfigurations accompanied the development of I-88 and I-355, and local governments including the Kane County Division of Transportation and Will County Division of Transportation implemented widening, signal modernization, and intersection redesigns to address increased traffic from commuter flows to employment centers like Chicago O'Hare International Airport-area logistics parks and manufacturing sites tied to companies headquartered in the Chicago metropolitan area.
Major intersections
Illinois Route 59 intersects multiple principal highways and municipal thoroughfares that serve regional mobility and freight movements. South to north, notable junctions include the interchange with I-55 near Plainfield, connections with I-355 and U.S. Route 34 adjacent to Naperville, an interchange with I-88 near Aurora, crossings of state routes such as Illinois Route 56 and Illinois Route 64, and its northern terminus at U.S. Route 20 in Elgin. These intersections interface with municipal arterial grids in jurisdictions like Aurora, St. Charles, and Bartlett, and provide access to commuter rail stations operated by Metra and freight connections on corridors used by carriers including BNSF Railway and Union Pacific Railroad.
Traffic and usage
Route 59 functions as a high-capacity urban arterial carrying commuter, retail, and freight traffic from suburban employment centers to Chicago and regional distribution hubs. Peak-period congestion is common near retail concentrations and interchanges serving Naperville and Aurora, with traffic studies by entities such as the Chicago Metropolitan Agency for Planning and county transportation departments documenting vehicle counts, peak-hour delays, and crash patterns influenced by access density. Transit-oriented developments near Metra stations along corridors served by Route 59 have increased multimodal demand, while commercial zones anchored by national retailers contribute to heavy turning movements and pedestrian interactions monitored by municipal planning commissions in St. Charles and Elgin.
Future developments and improvements
Planned improvements along the corridor involve capacity upgrades, intersection safety enhancements, and multimodal investments coordinated among the Illinois Department of Transportation, county agencies, and municipal governments. Projects under consideration include signal system upgrades informed by traffic modeling from the Chicago Metropolitan Agency for Planning, addition of bicycle and pedestrian facilities consistent with local comprehensive plans in Naperville and Aurora, and intersection reconfigurations to reduce conflict points near retail clusters collaborating with developers and agencies like the Federal Highway Administration. Long-term strategies reference regional initiatives to integrate transit service expansions with arterial management measures to improve reliability for commuters traveling between suburbs and employment centers such as Downtown Chicago, O'Hare International Airport, and suburban industrial parks.
