San Juan has a good transportation network, as most of the routes that connect with the rest of the country are in very good maintenance condition. The more important routes are the RN40, which crosses from north to south and joins the provinces of Mendoza and La Rioja, the RN20, which links San Juan with the city of Buenos Aires and Cordoba, the RN150, which allows a connection to the country of Chile. There are important projects under way that will allow a connection with the province of La Rioja, the entire northern Fertile Valley, Jáchal and Church, and with Chile, which will be a vital part of the strategic corridor Pacific-Atlantic .
