Iowa City sits on both banks of the Iowa River, with the University of Iowa campus spread along the water through the middle of town. I-80 runs along the north edge of the city toward Des Moines and the Quad Cities, and I-380 heads north from Coralville toward Cedar Rapids. US 218 runs along the west side, sharing the road with I-380 toward the Eastern Iowa Airport, and US 6 follows Riverside Drive and continues through Coralville. IA 1 heads northeast toward Solon and south toward Kalona.
Inside the city, Dubuque Street brings traffic from I-80 into downtown along the river, Burlington Street carries much of the east-west traffic, and First Avenue and Mormon Trek Boulevard serve the east and west sides. Downtown has a pedestrian mall and many one-way streets, and the campus is laced with permit-only lots. The older neighborhoods have narrow streets and alleys, while Coralville and North Liberty have newer subdivisions with driveways and attached garages. Dubuque Street near the river is also one of the first roads to close when the Iowa River runs high.
The Eastern Iowa Airport near Cedar Rapids is the nearest commercial airport. Cambus, the free university bus system, serves campus, and Iowa City Transit and Coralville Transit cover the rest of the area. Plenty of students and faculty don't need a car every day, which means many cars sit for days or weeks at a time and come back to dead batteries and soft tires. Many students also bring cars from out of state, and a car used to a milder climate often meets its first real Iowa winter with an old battery.
