The Galician road network includes autopistas and autovías connecting the major cities, as well as national and secondary roads to the rest of the municipalities. The Autovía A-6 connects A Coruña and Lugo to Madrid, entering Galicia at Pedrafita do Cebreiro. The Autovía A-52 connects O Porriño, Ourense and Benavente, and enters Galicia at A Gudiña. Two more autovías are under construction. Autovía A-8 enters Galicia on the Cantabrian coast, and ends in Baamonde (Lugo province). Autovía A-76 enters Galicia in Valdeorras; it is an upgrade of the existing N-120 to Ourense and Vigo.
