The Rhineland Route project (or “Rijnland Route” in Dutch) is a major transportation project in a part of Holland through which the Rhine river flows on its way towards Rotterdam, and involves construction of an expressway connecting the cities of Katwijk (via the A44 motorway) and Leiden (on the A4). The main contract, awarded to the COMOL5 consortium – a joint venture involving Mobilis B.V., VINCI Construction Grands Projets S.A.S. and DEME Infra Marine Contractors B.V. – is of the DBFMO type (design, build, finance, maintain and operate). The project includes rebuilding a motorway junction at Leiden West, constructing a new 4-km roadway that includes a 2.2-km tunnel, widening 12 km of motorway, and making necessary adjustments on the A4 and A44. Major challenges on the project include limited space due to the region’s very high population density (the highest in Holland, which itself has the highest density for any European country of comparable size or greater). Another unusual challenge is the high water table, which is typically just 60 cm below ground level in the project area.
Considering the constructor’s responsibility for maintaining and operating the infrastructure for a 15-year period, and handing over to the client in good condition at the end of that time, great care was taken to use well-selected, high-quality key components in the construction of the various structures. For the bridges, mageba was selected to design and manufacture a wide range of bearings and expansion joints, as follows:
With nearly all of these components now having been delivered to site and installed, we are glad to have had the opportunity to support this important infrastructure project with a range of bridge products as diverse as the regions through which the River Rhine flows on its long journey to the North Sea.
