Traffic on the A12 highway towards Antwerp is experiencing significant delays this morning following a collision involving three trucks near Willebroek. The incident, which occurred on February 20, 2026, has resulted in the closure of two lanes, causing a substantial traffic backlog. Motorists are advised to seek alternative routes, with the E19 being recommended as a detour.
The accident took place on the A12 between Brussels and Antwerp, and emergency services were quickly dispatched to the scene. While initial reports indicated two lanes were blocked, traffic is now passing over two lanes, though significant delays remain. The Flemish Traffic Centre is closely monitoring the situation and providing updates to drivers.
Details of the Incident and Traffic Impact
According to reports, the collision involved three heavy goods vehicles. The incident is causing delays of approximately 25 minutes for drivers traveling towards Antwerp, starting from Londerzeel. The Flemish Traffic Centre is urging drivers to consider alternative routes, specifically the E19, to avoid the congestion.
This incident follows a pattern of traffic issues on the A12. In January 2025, the Bevrijdingstunnel section of the A12 was completely closed after a truck accident, as reported by Brussels Morning. More recently, the Agency for Roads and Traffic (Agentschap Wegen en Verkeer) implemented safety measures at the A12/Bevrijdingstunnel split to prevent similar incidents. These measures included the installation of signalization posts and the removal of a confusing traffic sign, according to VRT News.
Recent Safety Improvements and Ongoing Concerns
The installation of signalization posts at the A12/Bevrijdingstunnel split was a direct response to previous accidents where trucks failed to navigate the junction correctly, colliding with the central curb. Gilles Van Goethem of the Agency for Roads and Traffic stated that the goal of these measures is to make the choice point clearer for drivers and reduce the number of accidents. The agency also removed a traffic sign deemed confusing, aiming to further simplify navigation at the critical junction.
However, despite these improvements, incidents continue to occur on the A12. On February 19, 2026, another incident occurred on the A12 towards Antwerp, near Ekeren, involving a car and two trucks. A person was briefly trapped and required assistance from the fire department, as reported by MSN.
What to Expect Next
Authorities are working to clear the scene of the latest accident and restore normal traffic flow on the A12. The Agency for Roads and Traffic will likely continue to assess the situation and consider further safety measures to mitigate the risk of future collisions. Drivers traveling towards Antwerp should continue to monitor traffic reports and allow for extra travel time.
