France: A14 tunnel closed for 12 straight days, towards Paris, between Nanterre and Pont de Neuilly
DiRIF is closing the A14 tunnel, towards Paris, 24 hours a day, from 18 to 30 October, to renew the tunnel''s safety equipment — a much longer closure than the usual overnight works in the Île-de-France. Anyone entering Paris from the west should expect a detour for nearly two weeks.
DiRIF (the Île-de-France road authority) is closing the A14 tunnel, towards Paris, between the junction with the A86 at Nanterre and the Pont de Neuilly, 24 hours a day, from 18 to 30 October, to renew the tunnel’s safety equipment. This is well outside the usual pattern of Île-de-France overnight closures, which normally last one night or a few nights in a row: this one runs for twelve uninterrupted days, ending at 05:30 on 30 October.
DiRIF’s alert, published on 6 October, gives no alternative route. Anyone entering Paris via the A14 from the west (Normandy, A13) should expect a detour for the whole period — typically via the A86 or the Périphérique itself, depending on time and origin. The corresponding traffic notice keeps tracking the closure and will be updated if DiRIF publishes a recommended detour or changes the dates.
