As part of the work on the JAG (Jonction Autoroutière du Grand-Saconnex), the A1 motorway will be closed at Versoix, to users coming from Lausanne and heading towards the airport, on the nights of 18 to 19 November, and 19 to 20 November from 00:00 to 4:00. A diversion route will be set up on the cantonal network. Additional travel times are to be expected on these two evenings in the Lausanne-Airport direction.
