Transportation
Chicago is a major transportation hub in the United States and North America. It is an important component in global distribution, as it is the third-largest inter-modal port in the world after Hong Kong and Singapore.
The city of Chicago has a higher than average percentage of households without a car. In 2015, 26.5 percent of Chicago households were without a car, and increased slightly to 27.5 percent in 2016. The national average was 8.7 percent in 2016. Chicago averaged 1.12 cars per household in 2016, compared to a national average of 1.8.
Due to Chicago's wheel tax, residents of Chicago who own a vehicle are required to purchase a Chicago City Vehicle Sticker. In established Residential Parking Zones, only local residents can purchase Zone-specific parking stickers for themselves and guests.
Chicago since 2009 has relinquished rights to its public street parking. In 2008, as Chicago struggled to close a growing budget deficit, the city agreed to a 75-year, $1.16 billion deal to lease its parking meter system to an operating company created by Morgan Stanley, called Chicago Parking Meters LLC. Daley said the "agreement is very good news for the taxpayers of Chicago because it will provide more than $1 billion in net proceeds that can be used during this very difficult economy."
The rights of the parking ticket lease end in 2081, and since 2022 have already recouped over $1.5 billion in revenue for Chicago Parking Meters LLC investors.
Eight mainline and four auxiliary interstate highways (41 (mostly in Wisconsin), 55, 57, 65 (only in Indiana), 80 (also in Indiana), 88, 90 (also in Indiana and Wisconsin), 94 (also in Indiana and Wisconsin), 190, 290, 294, and 355) run through Chicago and its suburbs. I-490 is currently under construction on the west side of O'Hare Airport. Segments that link to the city center are named after influential politicians, with three of them named after former U.S. Presidents (Eisenhower, Kennedy, and Reagan) and one named after two-time Democratic candidate Adlai Stevenson.
The Chicago Skyway, which carries I-90, is the only toll road within the city limits and is operated by the Skyway Concession Company. The Skyway leads into the Indiana Toll Road. The Illinois State Toll Highway Authority (known simply as the Illinois Tollway), operates several toll roads in the suburbs and throughout Northern Illinois, but none enter the City. I-Pass serves as the Illinois Tollway's primary electronic toll collection system. I-Pass and E-Z Pass are both accepted on the Skyway and Indiana Toll Road.
The Kennedy and Dan Ryan Expressways are the busiest state maintained routes in the entire state of Illinois.
The Northern Illinois Transit Authority (NITA) coordinates the operation of three transit service boards: CTA, Metra, and Pace.
The Chicago Transit Authority (CTA) handles public transportation in the City of Chicago and a few adjacent suburbs outside of the Chicago city limits. The CTA operates an extensive network of buses and a rapid transit elevated and subway system known as the Chicago "L" (or just the "L") (short for "elevated"), with lines designated by colors. These rapid transit lines also serve both Midway and O'Hare Airports. The CTA's rail lines consist of the Red, Blue, Green, Orange, Brown, Purple, Pink, and Yellow lines. The Red and Blue lines both offer 24‑hour service which makes Chicago one of a handful of cities around the world (and one of three in the United States, the other are New York City and Philadelphia) to offer rail service 24 hours a day, every day of the year, within the city's limits.
Metra (NITA's Commuter Rail Division), one of the busiest commuter rail systems in the United States, operates eleven commuter rail services out of four rail terminals in downtown Chicago. It connects the City with suburban Cook County and the five collar counties of DuPage, Kane, Lake, McHenry, and Will. One line continues onto Kenosha, Wisconsin. Starting in 2027, there will be a new inter-city service to Rockford, Illinois.
Pace (NITA's Suburban Bus Division) provides bus and paratransit service in over 200 surrounding suburbs with some extensions into the City as well. A 2005 study found that one quarter of commuters used public transit.
Ventra serves as the fare payment system for CTA and Pace. Metra tickets are also sold on the Ventra mobile app. A monthly Regional Connect Pass or Regional Day Pass can be purchase alongside a Metra ticket, allowing for unlimited rides for all three agencies.
The Northern Indiana Commuter Transportation District (NICTD) operates the South Shore Line, which provides commuter rail service from Millennium Station to Northwest Indiana. Since March 2026, it consists of two services: the Lakeshore Corridor to South Bend and the Monon Corridor to Munster/Dyer.
Greyhound Lines provides inter-city bus service to and from the city at the Chicago Bus Station, and Chicago is also the hub for the Midwest network of Megabus.
Amtrak long distance and inter-city rail services originate from Chicago Union Station. Chicago is one of the largest hubs of passenger rail service in the nation. The services terminate in Port Huron, St. Paul, the San Francisco Area, New York City, New Orleans, Portland, Oregon, Seattle, Miami, Milwaukee, Carbondale, Quincy, Boston, St. Louis, Kansas City, Grand Rapids, Los Angeles, San Antonio, and Pontiac, Michigan. Future service will terminate at Moline.
Chicago has a total of four active rail terminals: Chicago Union Station, Ogilvie Transportation Center, LaSalle Street Station, and Millennium Station. Amtrak only serves Union Station, while Metra serves all four stations. The South Shore Line services uses Millennium Station as its Chicago terminal.
In July 2013, the bicycle-sharing system Divvy was launched with 750 bikes and 75 docking stations. It is operated by Lyft for the Chicago Department of Transportation. As of July 2019, Divvy operated 5800 bicycles at 608 stations, covering almost all of the city, excluding Pullman, Rosedale, Beverly, Belmont Cragin and Edison Park.
In May 2019, The City of Chicago announced its Chicago's Electric Shared Scooter Pilot Program, scheduled to run from June 15 to October 15. The program started on June 15 with 10 different scooter companies, including scooter sharing market leaders Bird, Jump, Lime and Lyft. Each company was allowed to bring 250 electric scooters, although both Bird and Lime claimed that they experienced a higher demand for their scooters. The program ended on October 15, with nearly 800,000 rides taken.
Chicago Terminal is the largest rail hub in North America. All six Class I railroads and two “switcher” railroads (BRC and IHB) meet in Chicago, with 27 major intermodal rail yards in the region.. As of 2002, severe freight train congestion caused trains to take as long to get through the Chicago region as it took to get there from the West Coast of the country (about 2 days). According to U.S. Department of Transportation, the volume of imported and exported goods transported via rail to, from, or through Chicago is forecast to increase nearly 150 percent between 2010 and 2040. CREATE, the Chicago Region Environmental and Transportation Efficiency Program, comprises about 70 programs, including crossovers, overpasses and underpasses, that intend to significantly improve the speed of freight movements in the Chicago area.
Chicago is primarily served by O'Hare International Airport (ORD), the world's busiest airport measured by airline operations, on the far Northwest Side, and Midway International Airport (MDW) on the Southwest Side. Both airports are owned and operated by the Chicago Department of Aviation (CDA).
O'Hare is major hub for American Airlines and United Airlines. As of 2025, O'Hare is the world's busiest airport by aircraft movements. As of August 2026, O'Hare has over 1,100 daily domestic flights to nearly 200 destinations in the United States and over 140 daily flights to nearly 70 international destinations. The CTA's Blue Line provides direct rail access to O'Hare from downtown 24 hours a day, seven days a week.
Midway is a major operating base for Southwest Airlines. As of July 2026, Midway has over 250 daily domestic flights to over 80 destinations in the United States. There are also international flights to Canada, Mexico, and the Caribbean. The CTA's Orange Line provides direct rail access to Midway from the Loop.
Gary/Chicago International Airport and Chicago Rockford International Airport, located in Gary, Indiana and Rockford, Illinois, respectively, can serve as alternative Chicago area airports, however they do not offer as many commercial flights as O'Hare and Midway. In recent years the state of Illinois has been leaning towards building an entirely new airport in the Illinois suburbs of Chicago.
The City of Chicago is the world headquarters for United Airlines, the world's third-largest airline.
The Port of Chicago consists of several major port facilities within the city of Chicago operated by the Illinois International Port District (formerly known as the Chicago Regional Port District). The central element of the Port District, Calumet Harbor, is maintained by the U.S. Army Corps of Engineers.
Iroquois Landing Lakefront Terminal: at the mouth of the Calumet River, it includes 100 acres (0.40 km2) of warehouses and facilities on Lake Michigan with over 780,000 square meters (8,400,000 ft2) of storage.
Lake Calumet terminal: located at the union of the Grand Calumet River and Little Calumet River 6 miles (9.7 km) inland from Lake Michigan. Includes three transit sheds totaling over 29,000 square meters (310,000 ft2) adjacent to over 900 linear meters (3,000 linear feet) of ship and barge berthing.
Grain (14 million bushels) and bulk liquid (800,000 barrels) storage facilities along Lake Calumet.
The Illinois International Port district also operates Foreign trade zone No. 22, which extends 60 miles (97 km) from Chicago's city limits.
