Interstate 90 in Illinois in the context of "Dan Ryan Expressway"

A variable- (also changeable-, electronic-, or dynamic-) message sign or message board, often abbreviated VMS, VMB, CMS, or DMS, and in the UK known as a matrix sign,is an electronic traffic sign often used on roadways to give travelers information about special events. Such signs warn of traffic congestion, accidents, incidents such as terrorist attacks, Amber/Silver/Blue Alerts, roadwork zones, or speed limits on a specific highway segment. In urban areas, VMS are used within parking guidance and information systems to guide drivers to available car parking spaces. They may also ask vehicles to take alternative routes, limit travel speed, warn of duration and location of the incidents, inform of the traffic conditions, or display general public safety messages.

Randolph Street is a street in Chicago, Illinois, United States. It runs east–west through the Loop, carrying westbound traffic west from Michigan Avenue across the Chicago River on the Randolph Street Bridge, interchanging with the Kennedy Expressway (I-90/I-94), and continuing west. It serves as the northern boundary of Grant Park and the Chicago Landmark Historic Michigan Boulevard District. Several large theaters, as well as city and state government buildings are on and adjacent to Randolph. Metra's Millennium Station is located under Randolph Street.

Interstate 290 (I-290) is an auxiliary Interstate Highway that runs westward from the Jane Byrne Interchange near the Chicago Loop. The portion of I-290 from I-294 to its east end is officially called the Dwight D. Eisenhower Expressway. In short form, it is known as "the Ike" or the Eisenhower. Before being designated the Eisenhower Expressway, the highway was called the Congress Expressway because of the surface street that was located approximately in its path and onto which I-290 runs at its eastern terminus in the Loop.

I-290 connects I-90 (Jane Addams Memorial Tollway) in Rolling Meadows with I-90/I-94 (John F. Kennedy Expressway/Dan Ryan Expressway) near the Loop. North of I-355, the highway is sometimes known locally as Illinois Route 53 (IL 53), or simply Route 53, since IL 53 existed before I-290. However, it now merges with I-290 at Biesterfield Road. In total, I-290 is 29.84 miles (48.02 km) long.

The Jane Byrne Interchange (until 2014, Circle Interchange) is a major freeway interchange near downtown Chicago, Illinois. It is the junction between the Dan Ryan, Kennedy and Eisenhower Expressways (I-90/I-94 and I-290), and Ida B. Wells Drive. In a dedication ceremony held on August 29, 2014, the interchange was renamed in honor of former Chicago mayor Jane M. Byrne (in office, 1979–1983).

First developed in the late 1950s and 1960s, over time the interchange in its original configuration became notorious for traffic jams. In 2004, it was rated as the country's third-worst traffic bottleneck, with approximately 400,000 vehicles using it per day. In a 2010 study of freight congestion (truck speed and travel time), the U.S. Department of Transportation ranked this section of I-290 as having the worst congestion in the United States. This led to an $800 million reconfiguration begun in 2013 and completed in December 2022.
