The Second Coen Tunnel is a tunnel under the North Sea Canal, next to the Coen Tunnel in Amsterdam. The tunnel was built in combination with a new highway connection, the Westrandweg, to the A5 motorway. The tunnel consists of 3 fixed lanes and two variable lanes which are opened in the direction where traffic is the heaviest. The goal of the Second Coen Tunnel is to lighten congestion which occurs before the original Coen Tunnel on the A8 motorway in the morning and the A10-West motorway in the evening.
