The main A1 toll highway Autostrada from Florence to Naples provides good north-south communications. The A24 heads east from Rome to the mountains of the Abruzzo. Other important highways in northern Lazio are the A12, which follows the coast north in the direction of Pisa in Tuscany and the Cassia and Cassia bis, which is the main road to Viterbo. Southern Lazio is served by the Pontina, which can get very crowded on summer weekends.
There is a good rail network. Most routes are north-south via Rome rather than east-west. Bus services are also available, if infrequent.
