Paris Métro Line 8

Paris Métro Line 8 (French: Ligne 8 du métro de Paris) is one of the sixteen lines of the Paris Métro. It connects Balard in the southwestern part of Paris to Pointe du Lac station in the southeastern suburbs, following a parabolic route on the Rive Droite of the Seine. The last line of the original 1898 Paris Métro plan, which opened in July 1913, it was initially intended to link Porte d'Auteuil and Opéra. With 105.5 million travellers in 2017, it is the network's eighth busiest line; at 23.4 km (14.5 mi) in length, it is also the second longest Métro Line after Line 13, and the longest fully straight line, as line 13 has branches. Along with Line 7, it serves the most stations of any line on the network, at 38. Line 8 interchanges with all but three other Métro lines (Line 2, Line 3bis and Line 7bis).

The line was substantially modified during the 1930s as Line 10 took over the western section. The current route serves the southwestern part of the city, the Grands Boulevards and Bois de Vincennes, ending in the southeastern inner suburbs through the communes of Charenton-le-Pont, Maisons-Alfort and Créteil, which the line reached in 1974 at Créteil – Préfecture station, after several extensions. The underground line was the first to connect the prefecture of one of the new departments of Île-de-France. The only Paris underground line to cross the Seine and its principal tributary, the Marne, above ground via a bridge between Charenton – Écoles and École Vétérinaire de Maisons-Alfort, it also crosses the Seine underground between Concorde and Invalides.
