Rotterdam: A Month of Disruptions on A16/A20. Detours for Trucks

From November 7 to December 7, 2025, truck drivers will face major changes in the Rotterdam area. Rijkswaterstaat is carrying out reinforcement works on the viaduct structure at the key Terbregseplein interchange, which connects the A16 and A20 motorways.

Due to the works, some ramps will be completely closed to traffic, causing disruptions on one of the Netherlands’ most important transit corridors. The most significant inconvenience concerns the ramp connecting the A20 to the A16 in the direction of Dordrecht (from the Hoek van Holland side), which will remain closed continuously for four weeks from Friday, November 7 at 22:00 until Sunday, December 7 at 08:00. In addition, there will be three weekend closures of the remaining A20-to-A16 connections (traffic from the Gouda side towards both The Hague and Dordrecht):
❌ November 7 (22:00) – November 10 (05:00)
❌ November 21 (22:00) – November 22 (23:59)
❌ December 6 (22:00) – December 7 (08:00)

Rijkswaterstaat warns that the disruptions may result in 10–30 minutes of additional travel time, and during rush hours or in the event of road incidents, delays could reach up to 60 minutes.

Detours for Heavy Vehicles

Depending on the direction of travel, transit traffic will be diverted as follows:
➡ Direction Dordrecht: A20 → A4 (Benelux Tunnel) → A15
➡ Direction The Hague: A20 → A13

⭕ Transport of Dangerous Goods will be directed onto designated diversion routes:
• A20 → A13 → new A16 section (Rottemeren Tunnel)
• alternatively: A20 → A12 → A27
