The redevelopment of the A36 – RN1019 interchange at Sevenans is aimed at improving traffic flows between the A36 motorway and the RN1019 main road. It is situated in the Territoire-de-Belfort department of eastern France and involves:
- Upgrading the RN1019 to 2×2 lanes along a 3.6 km stretch, including an 0.85 km new section
- Creating a new double-trumpet interchange between the A36 and the RN1019, including a link road approximately 1 km long with 2 single lanes and weave lanes
- Modifying the layout of the RN1019 between the link road to the RN1019 and the RD437
- Redeveloping the interchange between the RN1019 and the RD437 to avoid left-turns, and linking it to the RN1019, requiring new weave lanes to the RD25 interchange.
