Foundations of two anchor piers and a pivot pier

From around 1850 the Dutch government built a dense network of canals, rivers, bridges, and railways throughout the country. The photographic documentation of public works was a statutory part of the construction process. Accordingly, the photographer Pistoor and his sons recorded the building of the bridge over the Oude Maas River at Spijkenisse. The photographs convey a fascinating image of a country in motion.
