Grade Separation of Intersections on the Km 4 Ring Road, Sfax - Lot No. 2: RN13 and RN14 Intersections

The project aims to ease and secure traffic flow on the Km 4 ring road at the intersections with national roads RN13 and RN14. Two viaducts were built above these intersections to eliminate direct crossings between the traffic flows of the ring road and those of RN13 and RN14, thus allowing faster and safer vehicle movement from Tunis to Gabès (and vice versa).
