Netherlands – Engineering works and construction works – 31127608 Realiseren en in stand houden van de A27 Everdingen-Hooipolder

The A27 Houten-Hooipolder project covers a construction area with a total length of approximately 47 kilometers through the management area of ​​eight municipalities, three provinces, three water boards, four regional RWS services and three traffic centers. The route generally cannot handle the traffic volume in a number of places and is therefore the scene of the heaviest traffic jams in the country, as can be seen from the Traffic Top 50. In addition, the route crosses the three large and heavily trafficked rivers Lek, Boven Merwede and Bergsche Maas and the Amsterdam Rhine Canal.

The Boven Merwede is one of the busiest shipping routes in Europe. The contractor must mainly carry out the following work:

• Widening of the A27 with road widening and rush hour lanes;
• Removing the existing bridges over the Boven-Merwede near Gorinchem and realizing two new bridges including a movable part;
• Removing the existing bridges over the Bergsche Maas near Geertruidenberg and realizing two new bridges;
• Improving the flow at the Hooipolder junction by constructing a grade-separated connecting arch;
• Creating a new connection on the A27 Gorinchem De Groote Haar;
• Eliminating connection 34 of the A59 and, in compensation, improving the existing connection 33 with a connecting road to Geertruidenberg;
• Maintaining Third Party Infrastructure and RWS Infrastructure during the realization phase (with the exception of the existing Merwede Bridge and Keizersveer Bridge);
• Maintaining the RWS infrastructure north of km 20.1 during the use phase.
