Louisville sits on a long bend of the Ohio River, and three interstates converge downtown at the tangle of ramps known as Spaghetti Junction. I-64 runs along the riverfront and east toward Lexington, I-65 heads north across the river into Indiana and south toward Nashville, and I-71 angles northeast toward Cincinnati. Two beltways ring the city: the Watterson Expressway, I-264, about halfway out, and the Gene Snyder Freeway, I-265, through the outer suburbs. Several bridges connect Louisville with Jeffersonville, Clarksville and New Albany, and some of them carry tolls.
Inside the city, Bardstown Road runs through the Highlands with narrow lanes, tight parking and constant traffic, and Dixie Highway is the main corridor through the southwest. Preston Highway, Shelbyville Road and Brownsboro Road carry heavy traffic to the south and east. The Watterson backs up at rush hour near the I-65 interchange, and Spaghetti Junction is a hard place to break down, with short merges and almost no shoulder. Many older neighborhoods have alleys behind the houses, which gives a mechanic a quieter place to work than the street out front.
Louisville Muhammad Ali International Airport sits just south of downtown beside the fairgrounds and a major air cargo hub, so airport lots and the hotels along the I-65 corridor are frequent service stops. TARC runs buses across the metro, but most people drive, and many cross the river every day for work. During Derby season and big fairgrounds events, the south side jams up for days, which makes a repair at home or at the office even more useful.
