The Bergerhout roundabout in Alkmaar has been closed to regular traffic since the previous Monday, causing confusion, delays and detours around the city centre. The closure affects cyclists, pedestrians, motorists and truck drivers, while some people have criticised safety during the works, including the temptation for cyclists and scooter riders to use the pavement. Traffic controllers are helping road users navigate the changed routes.

The works aim to make the roads around the roundabout safer for cyclists, pedestrians and motorists and to add more greenery. They are expected to continue until mid-2027.
