The twin cities of Urbana and Champaign are divided by Wright Street, which runs north-south through the middle of the University campus. East-west streets have the same name in both cities, for the most part, but discrete numbering. If you are going to a building identified by a street address, you must know which city it is in. (For example, 1110 West Green Street, Urbana, is nearly 5 km away from 1110 West Green Street, Champaign.)
The Champaign-Urbana Mass Transit District (MTD), which carries more than 10 million passengers a year, offers excellent public transportation, including a novel "bikes on buses" program and an interactive trip planner.
