After the Second World War it soon becomes apparent that modern motorized traffic makes Alkmaar’s inner city burst at the seams. Not for the first time, since traffic congestion had been a major headache as far back as 1925. For centuries the medieval town-plan had been sufficient for traffic moving at walking speed. But those days were gone forever. A new traffic commission was established in 1950. Who could not come up with a solution. National urban planner prof. Wieger Bruin was asked to come up with a plan in 1955. He had been of assistance to many battered Dutch cities after the war. He was expected to deliver. He presented his first draft in 1958. He suggested draining all canals except for the Oudegracht and the Lindengracht and putting a thoroughfare through the town-centre from North to South. Many houses were to be demolished in the eastern part of town for this purpose. It came under heavy criticism which in turn led to new plans: in 1960, 1964 and 1967. In the end enough was enough. The population of Alkmaar would not have it. The Historical Society Alkmaar (then still known as Oud Alkmaar) led the resistance, especially its combative chairman Hendrik Ringers. And Mr. Hofstee, director of the insurance company ’t Hooge Huys, even had a donkey parade around town. A sign on his back read “Wieger Bruin is an ass”. A compromise was reached by widening the road-surface of the Luttik Oudorp and Verdronkenoord. The eastern district was not pulled down but rather renovated. The new Nieuwlanderbridge, crossing the Oudegracht, was prepared for a future wide thoroughfare which was never to cut through the old town-centre. By now, this bridge has vanished again. Near the latest, a replica of the former drawbridge in that place, the quay-walls still show how Wieger Bruin imagined cars would be given plenty of scope in the historic centre. After the failure of this project it might have been realized that a historic town cannot accommodate heavy motorized traffic. Restricted traffic zones are the only solution if we are to preserve our monumental heritage for future years.
