Bordeaux Métropole : une rocade stratégique
Objective: to make traffic flow! The issue of transport has become strategic in the metropolis, which is experiencing many slowdowns. The authorities are trying to find solutions.
Encircling Bordeaux and its metropolis for 45 km, dotted with 27 interchanges, the ring road is the structuring and strategic node for travel around and in the Gironde capital. With traffic ranging from 85,000 to 140,000 vehicles per day (including 6,000 to 18,000 heavy goods vehicles), it mobilizes the public authorities to propose facilities and experiments to make mobility more fluid. In addition to upgrading to 2×3 lanes, a set of avenues is being explored: developing reserved lanes to encourage carpooling, making the northeast quadrant more fluid, extending the ban on overtaking for heavy goods vehicles, reserving an emergency lane for public transport…
CONCERT
Concerning the conversion to 2×3 lanes between interchanges 4 to 16, the work decided in 2006 will be completed in 2023 with interchanges 7 to 9. This operation cost 268 million euros. The project to create an intersection between interchanges 17 and 18 (Villenave-d’Ornon) is currently in consultation. It aims to streamline traffic between interchanges 15 (A63 to Bayonne) and 19 (A62 to Toulouse). The work scheduled for autumn 2023 should be completed with commissioning in the spring of 2024, at a cost of 3.5 million euros. The State and Bordeaux Métropole decided in 2020 to restore the pedestrian-cycle crossing on the François-Mitterrand bridge. A walkway will be suspended from the cantilevered bridge. It will be 700 m long, and at least 3 m wide.
PROJECTS
Other developments are under study, such as the development between the A10 and interchange 26 to make the northeast quadrant more fluid. Benefits in terms of reducing congestion are also expected with the development, in a second phase, of interchange 26 with the RN89 towards Libourne. Other experiments are under study, such as increasing the occupancy rate per vehicle on the A10 through carpooling. A proportionate extension of the overtaking prohibition zones for heavy goods vehicles between interchanges 1 and 15 is concerned, but with the maintenance of singular points in order to avoid a wall of trucks. To improve collective public transport, the development of the emergency lane in a lane reserved for buses between interchanges 4 and 19 is under study. Finally, a consultation will take place at the beginning of 2023 for the development of the A63 in 2×3 lanes between Bordeaux and Salles (just after the junction for Arcachon!).
