Traffic heading towards Issoire → Clermont-Ferrand (South/North) will be diverted onto the left lane (fast lane) of the Clermont-Ferrand → Issoire (North/South) direction. This change will affect approximately 6 kilometers, between junctions n°10 « La Ribeyre » and n°8 « Coudes - Vic-le-Comte ».
Traffic will flow in both directions on the North/South lanes. The speed limit will be set at 80 km/h in the two-way traffic zone and 50 km/h in the diversion areas.
In the Clermont-Ferrand → Issoire (North/South) direction, the entry and exit ramps for junctions n°10 « La Ribeyre » and n°9 « Sauvagnat-Sainte-Marthe – Saint-Yvoine » will be closed. The exit ramp for junction n°8 « Coudes - Vic-Le-Comte » will also be closed, while the entry ramp will remain open.
Detour routes will be implemented to compensate for these closures.
