Delta Works

The Deltapark is well-reachable by public transport in summer, but there are limited services in winter. Take a train to Middelburg and from there, take bus line 133. The whole trip should take 2 to 2½ hr one way, from Rotterdam.

• 🌍 Deltapark Neeltje Jans (formerly Delta Expo), Faelweg 5, Vrouwenpolder (from Rotterdam, follow the A15 towards Europoort. Take exit 12 to Brielle/Middelburg/N57. Follow the N57 and after 10 km you will reach the Haringvlietdam. Keep on following the N57 and you will cross the Brouwersdam, and after 20 km more the Oosterschelde storm surge barrier. Neeltje Jans is indicated there), ☏ +31 111 655 655. 1 Apr-6 Nov 10:00-17:30 daily. The Deltapark Neeltje Jans is the most common entry point into the Delta Works, and if you're going to pick just one of the Delta Works points, this is probably your best bet. It's a theme park that goes beyond the storm surge barriers alone. There's an abundance of information about the history, construction and design of the Delta Works as a whole, and an opportunity to see the one of the barriers from the inside. The so-called "Delta-exposition" gives an overview of 2000 years of water works in the Netherlands and of course focusses on the Delta Works construction. The exposition about the dramatic 1953 flood that inspired the whole construction leaves a lasting impression and there's another fine exhibition dealing with whales, including a 22-meter whale skeleton. For children, there's a fun water park and some great slides. The "hurricane-machine" gives an idea of the power of wind and there's the skeleton of Max the Mammoth, who once lived here, to admire. There's seals and sharks to see, as well as other colourful fish and corals in the Bluereef aquarium. €21. (updated Jan 2018)

• 🌍 Expo Haringvliet, Haringvlietplein 3, Stellendam, ☏ +31 187 499-913. This is mainly a nice place for having a drink while getting the best view over the Haringvlietdam. You can also see a film and some pictures about the 1953 flood. €5. 

The fourteen works below are rarely in action, which in itself is a good thing. They are most often only active during storms. The first time the five major works were closed was January 3, 2018. In January 2018, the requirements for closing the weirs and dams were lowered to keep the Delta Works from rusting away and being able to be used when another extreme tide comes along. The listings below are sorted in chronological order of completion.

• 🌍 Stormvloedkering Hollandse IJssel (Algerakering). This weir in the Hollandse IJssel river is the oldest of the Delta Works, being put in usage on October 22, 1958. The weir was named after the former minister of Traffic and Water Management (Verkeer en Waterstaat), Jacob Algera, who stepped down from his position twelve days before the weir would be used first due to health concerns. The work had to be a weir as the Hollandse IJssel river is an important shipping route, and blocking it with a dam would severely harm the economy of not only the Netherlands, but also neighbouring countries such as Germany. From 2012-2017, the weir was closed on nine occasions. (updated Jan 2018)

• 🌍 Zandkreekdam. The Zandkreekdam is a dam separating the Veerse Gat from the Oosterschelde. It was opened on October 1, 1960, and was the second Delta Work completed. The dam is 830 m (2,720 ft) long, and can be crossed using the N256 provincial road. (updated Jan 2018)

• 🌍 Veerse Gatdam. The second dam listed as a Delta Work to be completed, closing off the Veerse Gat on the west side. The dam was completed on April 27, 1961 and runs between Walcheren and Noord-Beveland for 2.8 km (1.7 mi). The dam is crossed by the N57. Due to the completion of the dam, the fishing fleet of Veere had to move the day prior to completion to nearby Colijnsplaat. The Veerse Meer has since become a popular recreational area for water sports, especially windsurfing. (updated Jan 2018)

• 🌍 Grevelingendam. The Grevelingendam is a dam in between the islands of Schouwen-Duiveland and Goeree-Overflakkee. Work on the 6 km (3.7 mi) long dam began in 1958 and was completed in 1965. The dam was opened April 1 of that year. The dam is crossed by the N57. (updated Jan 2018)

• 🌍 Volkerakdam. The Volkerakdam is the fifth Delta Project, completed in 1969. The dam is a complex of three dams traversed by two roads; the A29 highway and the N59 provincial road. The Volkerak was closed off from the Hollands Diep by the dam, and because that area was part of the Scheldt-Rhineconnection, a popular and heavily used shipping route from the Rotterdam harbour to the harbour of Antwerp, Belgium was now involved in the Delta Works, which led to the creation of the Scheldt-Rhine canal. (updated Jan 2018)

• 🌍 Haringvlietdam. The sixth construction in the Delta Works project. The dam has locks to let ships through. The Haringvlietdam runs through the Haringvliet, connecting Voorne-Putten to Goeree-Overflakkee. The Haringvliet could, unlike other bodies of water, not just be closed off, as the Meuse and Rhine both ended into the Haringvliet. Instead, the Dutch built a complex of locks, about a kilometer long, which can move about 25 000 m³ of water per second. The dam consists of 17 locks, each of which is 56½ metres wide. The dam itself is just over 5 km (3.1 mi) long. (updated Jan 2018)

• 🌍 Brouwersdam. The Brouwersdam, built between 1962 and 1971, is another dam at the length of 6 km (3.7 mi), closing off the Brouwershavense Gat, subsequently creating the Grevelingenmeer. The water around the dam is up to 30 m deep. The closing of the Brouwersdam meant that some three thousand hectares of land were regained. Two years after completion, the N57 was opened, using most of the Delta Works to connect Zeeland to the mainland. A lock was installed in 1978, and Port Zélande, a marina and bungalowpark was opened halfway down the dam in the 1980s. A museum tramline runs across part of the dam as well. The Brouwersdam is also home to music event Concert at Sea since 2006. (updated Jan 2018)

• 🌍 Markiezaatskade. A 4 km (2.5 mi) long dam protecting the coast of North-Brabant near Bergen op Zoom, built between 1980 and 1983. Part of the dam was destroyed during a storm in 1982, delaying the completion somewhat. The dam runs mostly parallel to the Oesterdam, and together they make up several kilometers of the Scheldt-Rhine canal. (updated Jan 2018)

• 🌍 Oosterscheldekering (near the Deltapark Neeltje Jans). The Oosterscheldekering is one of the most impressive storm surge barriers in the region. The first plan aimed to place a dam here and close off the water behind it completely from the sea, turning the water into a freshwater lake. The project started with the creation of a couple of artificial islands in the 1960s and in 1973 about 5 km of the projected 9 km were dammed. Then, environmentalists and the fishery sector started protesting as the dams would cause environmental harm and destroy the local mussel and oyster industry. The project went back to the drawing board, and with a national cabinet crisis looming, it was decided that the remaining 4 km would become an open storm surge barrier that only closes when needed. It was opened on 4 October 1986 by Queen Beatrix. 

• 🌍 Oesterdam. A dam in between Tholen and Zuid-Beveland, blocking the east side of the Oosterschelde. At 10.5 km (6.5 mi) it is the longest dam of the Delta Works. The dam was built to separate salt and fresh water streams from each other to not destroy the life in the Oosterschelde. The north end of the dam houses the Bergse Diepsluis, which is built on top of the remains of the drowned city of Reimerswaal. (updated Jan 2018)

• 🌍 Philipsdam. The Philipsdam is a dam near to the Grevenlingendam, closing the Krammer and Volkerak off from each other. The dam connects the Grevenlingendam to Sint Philipsland. Construction was started in 1967 with the building of the work island of Plaat van Vliet. One and a half years later the island had several locks being built on it for private ships and well as large container ships. The dam was the last project on the island, being completed February 2, 1987; it has the N257 running its length. (updated Jan 2018)

• 🌍 Bathse Spuisluis. The Bathse Spuisluis is funnily enough not created to keep the water out of the Netherlands, but instead to flush the Volkerak, Zoommeer, Markiezaatsmeer and Scheldt-Rhine canal from time to time with fresh water. The Bathse Spuisluis does this in cooperation with the Bathse Spuikanaal. Construction began in 1980 and was completed seven years later. The Spuisluis is at the end of the 8.7 km (5.4 mi) long Spuikanaal, which is 140 m (460 ft) wide and 7 m (23 ft) deep. The Spuisluis has a capacity of 10 m³ per second, or 8.5 million m³ of water per day. (updated Jan 2018)

• 🌍 Maeslantkering, Havennummer 882, Hoek van Holland, ☏ +31 174 511-222. M-F 10:00-16:00, Sa Su hol 11:00-17:00. It was opened in 1997. This storm surge barrier is one of the largest moving structures in the world. The free visitor's centre, het Keringhuis, does not just explain the history of the Maeslantkering, but also deals with the wider context of Dutch water management. Several times per day, guided tours are provided for €4 per person (most are in Dutch, some in English). Check the website for time and reservations. Once a year (usually in September), the barrier is tested. On that day, the place might relatively crowded, but it's also possible to see the barrier from the top of the dune next to it. Free. (updated Jan 2018)

• 🌍 Hartelkering. The Hartelkering is the youngest of the Delta Works, being completed in 1997. The kering has been closed twice since its completion. Whether the Hartelkering will be closed or not is decided by BOS (Beslis en Ondersteunend Systeem), a computer system created for this purpose. The Hartelkering and Maeslantkering are always closed at the same time. (updated Jan 2018)
