Illinois Route 390
Illinois Route 390, previously known as the Elgin–O'Hare Expressway, is a significant part of northeastern Illinois's transportation network. This controlled-access toll road, now called the Elgin–O'Hare Tollway, spans approximately 9.8 miles (15.8 km) and serves as a vital connector for the region.
Route Description
IL 390 begins at U.S. Route 20, also referred to as Lake Street, in Hanover Park. It extends eastward, navigating through the locales of Wood Dale, Elk Grove Village, and Bensenville. The route terminates at an interchange with Illinois Route 83 and Thorndale Avenue, just shy of O'Hare International Airport.
Infrastructure and Technological Features
Illinois Route 390 stands out for being the first in the state to implement all-electronic toll collection, a system requiring the use of an I-Pass or E-ZPass. This predated the 2021 transition to all-electronic tolling on all roads managed by the Illinois State Toll Highway Authority. This electronic system eliminates cash transactions, aiming to streamline traffic flow and reduce congestion, though it historically caused backups during peak traffic times.
Traffic and Usage
According to the Illinois Department of Transportation, Illinois Route 390 experiences substantial traffic volumes. In 2003, daily traffic counts revealed approximately 39,600 vehicles on the western two miles and between 82,000 to 87,000 vehicles per day on the remainder of the road. These numbers highlight the route's importance in accommodating both local and through traffic.
Historical Context
The expressway was initially planned to alleviate congestion on local roads, such as Illinois Route 19, enhancing connectivity for communities like Roselle and Itasca. Its evolution from the Elgin-O'Hare Expressway to the Elgin-O'Hare Tollway underscores its ongoing role in regional traffic management and infrastructure development.
