Official WebsiteThe Grand Paris Express is the largest transportation project in Europe, a roughly 200-kilometer network of fully automated, driverless metro lines ringing the French capital and delivered by the Société des Grands Projets (formerly Société du Grand Paris). Comprising four new lines — 15, 16, 17, and 18 — together with major extensions of the existing Line 14, the roughly €35 billion program adds 68 new stations that knit the suburbs of the Île-de-France directly to one another and to Orly and Charles de Gaulle airports, bypassing the traditional bottleneck of central Paris. Engineered around driverless trains and architecturally ambitious stations designed by an international roster of architects, the network is opening line by line, reshaping how millions of residents across Greater Paris live, work, and move.
