The Piet Heintunnel was closed in both directions because of a malfunction in the C2000 emergency-services communication system. Emergency services have no coverage in the tunnel as a result.

The duration of the closure is unclear. Other city tunnels remain open, and the Piet Heintunnel can reopen once the malfunction has been fixed. Traffic can divert via the Nieuwe Leeuwarderweg and the IJtunnel, or via the Amsterdam Bridge and Zeeburgerdijk.
