By the early-1970s, Portugal's fast economic growth with increasing consumption and purchase of new automobiles set the priority for improvements in transportation. Again in the 1990s, after joining the European Economic Community, the country built many new motorways. Today, the country has a  road network, of which almost  are part of system of 44 motorways. Opened in 1944, the first motorway (which linked Lisbon to the National Stadium) was an innovative project that made Portugal one of the first countries in the world to establish a motorway (this roadway eventually became the Lisbon-Cascais highway, or A5).
