Intercity buses leave from the main bus station off Piazza XX Settembre, just southeast of the train station. However, for nearly all destinations, the train's a better option.
Bologna is linked to Milan, Florence and Rome by the A1 Autostrada del Sole. The A13 heads directly to Ferrara, Padua and Venice, and the A14 to Rimini and Ravenna. Bologna is also on the SS9 (Via Emilia), which connects Milan to the Adriatic coast. The SS64 goes to Ferrara.
Bologna is a major transport junction for northern Italy, with most trains arriving at Bologna Centrale station. The high-speed train to Florence (from €15) takes only 37 minutes. Other lightning-quick Frecciarossa links include Venice (from €15, 1¼ hours), Milan (from €20, 1¼ hours), Rome (from €20, 2¼ hours) and Naples (from €30, 3½ hours). Slower, less expensive trains also serve these destinations. Do as locals do and ask taxis to drop you directly at the underground high-speed platforms ('Stazione Alta Velocità') at the station (though occasionally Freccia trains are moved elsewhere).
Frequent trains connect Bologna with cities throughout Emilia-Romagna, including Modena, Parma, Ferrara, Ravenna and Rimini.
