The motorway had to be closed for Mons to France on Friday late in the morning, says Walloon Infrastructure Supplementary Financing Company (Sofico). Emergency repairs are carried out.
The tour was established by exit number 24 "Mons" and a side road to the motorway.
The re-opening is planned for the night from Saturday to Sunday.
The project aims to rebuild the entire width of the motorway at depth, repair the section ramps and the nine lower decks on which the motorway and the upper deck with a view of the road rest. It also aims to renew the drainage system, renew acoustic screens and reclaim the area of the Bois du Gard motorway.
