well as the roads leading to suburban villages, connect Ajaccio from the north - the site of Ajaccio forming a dead end blocked by the sea to the south. Only the Cours Napoleon and the Boulevard du Roi Jerome cross the city. Along with the high urban density, this explains the major traffic and parking problems especially during peak hours and during the summer tourist season. A bypass through several neighbourhoods is nearing completion. Communal bus services The Muvistrada provide services on 21 urban routes, one "city" route for local links and 20 suburban lines. The frequency varies according to demand with intervals of 30 minutes for the most important routes: A park and ride with 300 spaces was built at Mezzana in the neighbouring commune of Sarrola-Carcopino in order to promote intermodality between cars and public transport. It was inaugurated on 12 July 2010. Airport The city is served by an Ajaccio Napoleon Bonaparte Airport which is the headquarters of Air Corsica, a Corsican airline. It connects Ajaccio to a number of cities in mainland France (including Paris, Marseille, Nice, and Brive) and to places in Europe to serve the tourist industry. The airline CCM Airlines also has its head office on the grounds of the Airport. Port The port of Ajaccio is connected to the French mainland on an almost daily basis (Marseille, Toulon, Nice). There are also occasional links to the Italian mainland (Livorno) and to Sardinia, as well as a seasonal service serving Calvi and Propriano. The two major shipping companies providing these links are Corsica Linea and Corsica Ferries. Ajaccio has also become a stopover for cruises with a total of 418,086 passengers in 2007by far the largest in Corsica and the second-largest in France (after Marseille, but ahead of Nice/Villefranche-sur-Mer and Cannes). The goal is for Ajaccio to eventually become the premier French port for cruises as well as being a main departure point. The Port function of the city is also served by the commercial, pleasure craft, and artisanal fisheries (3 ports). Railways The railway station in Ajaccio belongs to Chemins de fer de la Corse and is located near the port at the Square Pierre Griffi. It connects Ajaccio to Corte, Bastia (3 h 25 min) and Calvi. There are two optional stops: Salines Halt north of the city in the district of the same name Campo dell'Oro Halt near the airport
