Before the tunnel was built, the Hem ferry and, to a lesser degree, the Schellingwouder bridge were the most important connections between Amsterdam and Zaandam, and this was a serious bottleneck for traffic. In 1959 5,800 vehicles were ferried daily and waiting times reached 45 minutes or more. In the 1950s inhabitants petitioned successfully for a tunnel under the North Sea Canal.
