candidates: 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 among one of the first countries in the world to establish a motorway (this roadway eventually became the Lisbon-Cascais highway, or A5). But, although a few other tracts were created (around 1960 and 1970), it was only after the beginning of the 1980s that large-scale motorway construction was implemented. In 1972, Brisa, the highway concessionaire, was founded to handle the management of many of the regions motorways. On many highways, toll needs to be paid, see Via Verde. Vasco da Gama bridge is the longest bridge in Europe. Continental Portugal's territory is serviced by three international airports located near the principal cities of Lisbon, Porto, Faro and Beja. Lisbon's geographical position makes it a stopover for many foreign airlines at several airports within the country. The primary flag-carrier is TAP Portugal, although many other domestic airlines provide services within and without the country. The government decided to build a new airport outside Lisbon, in Alcochete, to replace Lisbon Portela Airport, though this plan has been stalled due to the austerity. Currently, the most important airports are in Lisbon, Porto, Faro, Funchal (Madeira), and Ponta Delgada (Azores), managed by the national airport authority group ANA – Aeroportos de Portugal. A national railway system that extends throughout the country and into Spain, is supported and administered by Comboios de Portugal. Rail transport of passengers and goods is derived using the of railway lines currently in service, of which are electrified and about allow train speeds greater than . The railway network is managed by the REFER while the transport of passengers and goods are the responsibility of Caminhos de Ferro Portugueses (CP), both public companies. In 2006 the CP carried 133 million passengers and of goods. The major seaports are located in Sines, Lisbon, Leixões, Setúbal, Aveiro, Figueira da Foz, and Faro. The two largest metropolitan areas have subway systems: Lisbon Metro and "Metro Sul do Tejo" in the Lisbon Metropolitan Area and Porto Metro in the Porto Metropolitan Area, each with more than of lines. In Portugal, Lisbon tram services have been supplied by the "Companhia de Carris de Ferro de Lisboa" (Carris), for over a century. In Porto, a tram network, of which only a tourist line on the shores of the Douro remain, began construction on 12 September 1895 (a first for the Iberian Peninsula). All major cities and towns have their own local urban transport network, as well as taxi services.
