Paris Périphérique to Close Overnight: Outer Carriageway Shut 9pm–6am Between Portes Brancion and Bagnolet
The Paris ring road's outer carriageway closes between Porte Brancion and Porte de Bagnolet from 21:00 to 06:00 on the night of Oct 20–21; Sytadin rates the disruption severe. The Porte de Montreuil exit ramp is shut until Dec 17. This is a roadworks closure, unrelated to the curfew.
Why it matters
According to Sytadin, the Île-de-France road information service, the outer carriageway of the Paris Périphérique will be closed between Porte Brancion and Porte de Bagnolet (via the south and east of Paris) on the night of Tuesday October 20 to Wednesday October 21, from 21:00 to 06:00. Sytadin rates the expected disruption as severe. Note: this is a roadworks closure, separate from the curfew in force the same night.
Other closures the same night
The same night also brings partial closures on the A3 toward the provinces (Porte de Bagnolet to Rosny-sous-Bois) and the A6b toward Paris (L'Haÿ-les-Roses to Porte d'Italie). Signed diversions will be in place; check Sytadin before leaving and allow extra time.
Longer closure: Porte de Montreuil ramp
Separately, per the Bagnolet city hall announcement, the outer-carriageway exit ramp at Porte de Montreuil is closed from October 20 until December 17, 2026 for interchange reconstruction — unrelated to tonight's overnight closure.
