A truck lost several concrete blocks on the A4 at the De Nieuwe Meer junction this morning. This resulted in damage to the road and several lanes in the direction of Schiphol were closed.
Rijkswaterstaat expects to be busy repairing the road surface until at least 12 noon. It is best for traffic to take a detour via the A9, the ANWB advises. From the Amstel junction (on the A10) traffic will be diverted via the A2 and A9.
Update: The road is now open again.
