Transportation in Cincinnati includes sidewalks, roads, public transit, bicycle paths, and regional and international airports. Most trips are made by car, with transit and bicycles having a relatively low share of total trips; in a region of just over 2 million people, less than 80,000 trips are made with transit on an average day. The city is sliced by three major interstate highways, I-71, I-74 and I-75, and circled by a beltway several miles out from the city limits. The region is served by two separate transit systems, one on each side of the river. SORTA, on the Ohio side is about six times larger than TANK on the Kentucky side.
