Five Vehicles Collide Near Kooimeer Interchange on A9
A multi-vehicle pileup involving five cars and a hearse created significant traffic disruption on the A9 motorway toward Alkmaar on October 27, 2026. The crash occurred just before 18:30 near the Kooimeer interchange in Heiloo, according to NH Nieuws. Three ambulances and the Heiloo fire department responded to the scene, where two people sustained light injuries and were transported to the hospital.
The collision forced Rijkswaterstaat and road workers to close two lanes of traffic. The ANWB reported that motorists traveling from Akersloot faced severe delays exceeding one hour as the remaining traffic was funneled past the crash site via a single open lane. Four of the damaged vehicles required towing, while one car managed to drive away from the scene under its own power. Authorities cleared the affected lanes later that evening.
