Lescar, Thèze and Garlin. At Langon, the A65 joins on to the A62, which continues to Bordeaux. The A65 was opened in 2010, and was at the time France's most expensive autoroute. Several more minor routes also serve Béarn. The Route Nationale 134 links the south of Pau with Somport in the Aspe Valley. Several mountain roads link Somport with Spain. Rail Three railway lines serve Béarn. The first of these is the Toulouse to Bayonne railway, which was opened in stages between 1861 and 1867. Several rail stations are located on this line, including those of Coarraze-Nay, Assat, Pau, Artix, Orthez and Puyoô. The Puyoô to Dax railway line enables trains to run from Béarn to Bordeaux. Both these railway lines are served by TGV, Intercités and TER. The third railway line, the Pau to Canfranc line, serves the south of Béarn. It was put into service between 1883 and 1928. However, the railway line been partially closed since 1970. This is because in 1970, a bridge carrying this rail line over the Gave d'Aspe was destroyed by a train derailment; SNCF consequently closed the line south of the Gare d'Oloron-Sainte-Marie. An additional section of the line, between Oloron-Sainte-Marie and Bedous, was reopened by SNCF in 2016. Canfranc Railway Station is located within Spain and is also served by the Spanish Jaca to Canfranc railway. International rail transport between Béarn and Aragon was thus previously possible using this route. In 2013, the regional governments of Aragon and Aquitaine agreed to take steps to further the economic links between their two regions, including possibly reopening the Pau-Canfranc railway line all the way to Canfranc Station. The two governments hope to have the line fully reopened by 2020. A fourth railway line once linked Puyoô rail station to that of Mauléon-Licharre. This line opened in two stages between 1884 and 1887; it was closed to passengers in 1968 and to freight in 1989. The line was officially abandoned in 1991. A branch of this line ran from Autevielle to Saint-Palais. This branch is also now closed.
