Transportation Information

Chicago’s public transportation system is run by the Chicago Transit Authority. The CTA operates the nation's second largest public transportation system and covers the City of Chicago and 40 surrounding suburbs. On an average weekday, approximately 1.6 million rides are taken on the CTA.

CTA runs both trains and buses. The train system is often called the ‘L’ and runs on both elevated and underground lines. Trains are accessed with fare cards which can be purchased within most stations and in many outside retail locations. There are eight train lines, most of which converge in the downtown “Loop.”

There are 140 bus routes that run on streets throughout the city. Bus fare is also paid by fare card, but can also be purchased with cash.

See maps of the CTA.

The Chicago Transit Authority has created a list of planned reroutes and service disruptions as necessitated by planned road closures during the Summit weekend. This list, as well as tips for making your commute on the CTA run smoothly, can be found on their website.

Much more information about Chicago’s public transportation system, including notifications about route delays and a trip planner, can be found at the CTA web site.

During the summit this May, the city of Chicago will be relying on the “Notify Chicago” system to keep residents and visitors updated on traffic issues. This alert system will inform users about street closures, bus reroutes, and potential delays. To sign up for this free text, email, or phone alert service, please visit the Notify Chicago website.
