A13 Section to Close for Extended Saint‑Cloud Tunnel Reinforcement

Overview

• Authorities will close the A13 in the Paris-to-province direction between the périphérique and Vaucresson to carry out reinforcement work on the Saint‑Cloud tunnel.
• The affected A13 stretch handles about 80,000 vehicles a day, so the shutdown will redirect large volumes of traffic onto nearby motorways and local roads.
• The government announced staged A14 toll relief, making the route free for Paris→province weekday traffic first and planning free two-way use during the summer holidays to absorb diverted cars.
• Public transport measures include five additional peak-hour express bus runs on the A14 corridor and easier station parking to encourage drivers to switch modes.
• The A86 duplex remains tolled, which could create local bottlenecks near Vaucresson and raise congestion risks for commuters in western Paris suburbs.
