Project description

Commissioned by Rijkswaterstaat, A4all – a consortium comprising VolkerWessels, Heijmans and Boskalis – is constructing a highway between the A4 near Delft and the Kethel square near Schiedam, in the Netherlands. Work started on the project in April 2012 and is planned to continue until late 2015.

The transition of the A4 between Delft and Schiedam will reduce the traffic on the A13 and will improve mobility in the area. The highway runs through the green zone between Delft and Schiedam and along the residential areas of Delft, Schiedam and Vlaardingen. The aim is to make the A4 between Delft and Schiedam one of the best-adapted highways in the Netherlands.

In addition, a range of special adaption measures have been taken in order to preserve the natural and recreational value along with the environment. For this purpose, part of the highway was sunk or half-sunk into the landscape, the A4 between Schiedam and Vlaardingen goes through a land tunnel, and all sorts of extra noise-reduction measures have been taken. In order to counteract cutting into the natural habitats of flora and recreation networks, the decision was made to build an eco-aquaduct, the largest in Europe at the time of its design.
