Viadukt Nagold

The first foundations, piers and round arches were built from solid concrete, as steel was already being used exclusively in the defence industry at this time. In 1953, the construction of reinforced concrete began. The new piers are hollow on the inside and some of their reinforced concrete walls are only 40 centimetres thick. Due to the lower dead weight of the bridge, a much simpler foundation was possible.

The total cost of construction in 1953/54 was two million marks. The bypass did not lead to a desolation of the city centre, as feared by many retailers.

In 2009/2010, the viaduct underwent extensive concrete renovation work.
