Road enlargement motorway A1-A6, Diemen-Almere

The A1/A6 project is one of the five sub-projects for Rijkswaterstaat that are included in the upgrading of the road network linking Schiphol Airport, Amsterdam, and Almere (SAA). The total length of the SAA link is 40 kilometers. Boskalis, together with partners, is responsible for the section from the Diemen intersection to Almere, a distance of approximately 23 kilometers.

The enlargement of the A1/A6 involves the reconstruction and widening of this section of the motorway. The A1 and the A6 between the Diemen intersection and the Hollandse Brug will become a road with 2x5 lanes. The A6 from the Hollandse Brug to the Hoge Ring near Almere will be 4x2 lanes. Reversible lanes will also be built on the entire A1/A6 section. The enlargement of the A1/A6 will also involve the construction of a permanent bypass at the Diemen intersection from the A9 to the A1. SAAone will build a total of 70 new engineering structures, including the cantilever bridge crossing the Amsterdam-Rhine Canal, the doubling of the Hollandse Brug bridge across the Gooimeer and the new aqueduct near Muiden as the most eye-catching features. The aqueduct that takes the River Vecht across fourteen lanes is the widest in Europe. After the completion of the construction stage in mid-2017, SAAone will maintain the work for 25 years.

Coastal protection, St. Petersburg

St. Petersburg is a UNESCO World Heritage City, but its location along the River Neva means that it has been threatened by over 300 floods since its founding by Peter the Great in 1703. The completion of the new 25 km long storm-surge barrier across the Gulf of Finland ensures that the city will no longer be vulnerable to high tides and devastating floods. As a result of the new Flood Protection Barrier, however, the old winding access channel had to be replaced with a new, straighter, more easily navigable channel.

Cleanup, Zellingwijk area

The Zellingwijk quarter of the village of Gouderak was built in the middle of the last century. In the early 1980s it became clear that the soil underneath this residential area was heavily contaminated as a result of the dumping of waste - mainly mineral oils and pesticides. The homes built on the site were subsequently demolished in the mid-1980s. Pending definitive remediation work, a layer of concrete / asphalt was applied to seal the site.

The archipelago consists of some 30 islands with a total of 160 km of shoreline and has a population of 800,000. Whereas the surface of Bahrain in the year 1960 was around 650 km2, the last decennia have seen a steady increase in the surface till a respectable figure of 740 km2 in 2007. This increase has been achieved by a various number of small and mayor reclamation projects.

Port expansion, Gijón

The Spanish port of Gijón on the Bay of Biscay processes more than 12 million tonnes of bulk goods annually. With the expansion of global trade and increasing ship sizes, the terminal was lacking capacity to handle the traffic. The maximum draft for the ships of 18 meters is another obstacle to the development of the port. So the Port Authority of Gijón developed a plan for additional modern facilities in an area measuring 145 hectares to the north of the existing port. This includes a bulk terminal with a transfer capacity of more than 25 million tons and a storage area measuring 60 hectares for a maximum of 2 million tons of coal and iron ore a year.
