Interstate 88 (Illinois) — Ronald Reagan Memorial Tollway

Route and key places

The roadway begins near the city of Silvis in western Illinois and travels eastward across a variety of landscapes — small cities, agricultural areas, and suburban corridors — before reaching its eastern terminus near Hillside in the Chicago area. Along the way it provides access to regional centers such as the Quad Cities, portions of the Fox Valley, and several outer suburbs of Chicago.

Characteristics and management

I-88 combines limited-access interstate standards with segments that function as a tollway. The tolled portions are managed as part of Illinois' toll network and accept electronic transponders commonly used in the state. Maintenance and operations involve state transportation agencies and toll authorities responsible for roadway upkeep, signage, and traffic management.

History and naming

The roadway follows alignments that were previously designated under state route numbers before being incorporated into the Interstate system during the late 20th century. In recognition of the 40th U.S. president, the tollway received the honorary Ronald Reagan name, a designation used in signage and official references.

Uses and importance

I-88 is important for both regional commuting and freight movement. It links manufacturing and agricultural areas in western Illinois with distribution centers and interchanges serving the Chicago metropolitan region. The corridor also supports economic activity in smaller towns it passes and serves as an alternative east–west route to other interstates in northern Illinois.

Notable facts
