The closure comes in light of the ongoing construction work of a new railway connection between Luxembourg City and Bettembourg.
The A3 will be shut between the Gasperich and Bettembourg intersections from 8pm on 21 May until 6am on 24 May. Diversions will be installed via the A13, A4, and A6 motorways.
The Aire de Berchem will also be affected by the construction work. The Shell petrol station cannot be accessed from 6pm on Friday until 6am on Monday. Similarly, the Aral petrol station will be inaccessible during the same period.
