By the middle of the 19th century, Rotterdam was already one of the largest port cities in the world, mainly because of transshipment of goods from Germany to Great Britain. The increase in shipping traffic created a capacity problem: there were too many branches in the river delta, making the port difficult to reach.

In 1863, a law was passed that allowed for the provision of a new canal for large ocean-going ships from Rotterdam to the North Sea. [[Hydraulic engineering|Hydraulic engineer]] [[Pieter Caland]] was commissioned to design a canal cutting through the "Hook of Holland” and to extend the Mouth of Rhine to the sea. The designs for this were already done back in 1731 by [[Nicolaas Kruik|Nicolaas Samuelsz Cruquius]] but the implementation could no longer be postponed to prevent the decline of the harbour of Rotterdam.

Construction began on 31 October 1863. The first phase consisted of the expropriation of farm lands from [[Rozenburg]] to [[Hook of Holland]].

During the second phase two dikes were built parallel to each other, which took 2 years. Caland proposed to extend the dikes 2&nbsp;km into the sea to disrupt the coastal sea currents and decrease silt deposits in the shipping lane.

Upon the completion of the dikes, the third phase began by the digging of the actual waterway. This began on 31 October 1866 and was completed three years later. The large amounts of removed soil were in turn used to reinforce other dams and dikes.

The last phase consisted of the removal of the dam separating the new waterway from the sea and river. In 1872, the Nieuwe Waterweg was completed and Rotterdam was easily accessible.

Because of the currents and erosion, the shipping lane has been widened somewhat. Yet because of the [[Draft (hull)|draft]] of today's [[supertanker]]s, it needs to be dredged constantly.

In 1997, the last part of the [[Delta Works]], the [[Maeslantkering]], was put in operation near the mouth of the Nieuwe Waterweg. This storm surge barrier protects Rotterdam against north westerly [[Beaufort scale|Beaufort]] Force 10 to 12 storms.
