| | Chicago has two major airports, O’Hare International, one of the busiest airports in the world, lies in the northwest part of the city. Before it took over much of the business in the 70s Chicago Midway in South Side was the area’s main airport. Some people prefer Midway since it is less busy. |
| The Chicago Transit Authority operates buses, subways, and elevated and ground-level trains. It's a very reliable system. Chicago is also a big motor city, though. A third of its people drive to work each day. The main downtown artery is Wacker Drive, a two-story highway that runs alongside the river. |
