Arup’s role covers design, procurement and site supervision of a 6.6km dual carriageway and a 1.4km tolled bridge. The new link will act as a bypass to the south of Frederikssund.

"We consider this project as being technically challenging because of the archeological situation in and around the Roskilde Fjord and the environmental impact on the Natura 2000 area,” said Jens Holmboe, the director of Vejdirektoratet’s construction division.

The work will be carried out across several Arup offices in Europe and remit covers the entire design from geotechnics, highways, drainage and bridge design to environmental, maritime and water engineering.

"We are very pleased to have Arup on this project. It is great to have Arup now permanently based in Denmark, bringing new ideas and an international approach which will eventually lead to an improvement of the overall performance on our projects," said Vejdirektoratet project director Erik Stoklund Larsen.

"This project is a game changer for Arup in Denmark because of its size and duration,” said Sander den Blanken, Arup’s bridges and civil structures practice leader for the Europe region. “It is also a firm step in the right direction of developing our infrastructure practice in Scandinavia in line with our strategy. Therefore I am extremely delighted and proud of the performance of our team."

Construction is due to start in 2016, and the opening of the link is expected in 2019.
