Dan Ryan Expressway

The Dan Ryan Expressway, designated as Interstate 90/94, is an arterial traffic corridor located in Chicago, Illinois. This major route extends from the southern boundary of downtown Chicago at the interchange with the Stevenson Expressway (I-55) to its southern terminus near the suburb of 95th Street. The Dan Ryan connects downtown Chicago to the southern neighborhoods of the city and serves as a critical artery for commuter travel and freight movement.

The corridor is characterized by heavy traffic, particularly during peak commuting hours, as it facilitates access for a population of over 2.7 million people residing in the Chicago metropolitan area. It plays a vital role in regional connectivity, linking residents to business districts, healthcare facilities, and educational institutions, while also supporting freight movement essential for the local economy.

Notable destinations accessed via the Dan Ryan Expressway include the United Center, home to the NBA's Chicago Bulls and NHL's Chicago Blackhawks, as well as several significant neighborhoods and parks throughout the South Side of Chicago. The expressway frequently experiences congestion, especially during rush hours, leading to ongoing infrastructure planning and upgrades to improve traffic flow. Seasonal travel demand may also influence congestion patterns, as the corridor is a critical route for event attendees and commuters alike.

In recent years, transportation authorities have focused on maintenance and enhancement projects along the Dan Ryan to address traffic volumes and improve safety, underscoring its economic significance within the regional transportation network.
