However, most downtown streets are one-way streets, and we strongly recommend that you carry a good city map. Getting around downtown Chicago is easiest on foot, but the bus service is excellent for longer journeys. Bus 151, for instance, will take you through downtown, into Lincoln Park and Lake View and beyond. Bus 146 can take you to the Museum Campus, where the Field Museum of Natural History, Shedd Aquarium and Adler Planetarium are located. Travelers by car may bypass downtown traffic by taking Lower Wacker Drive, a quick route beneath street level, running along the Chicago River.
Midway is more convenient to downtown than O Hare but is served by fewer airlines.
