The forthcoming 3rd Limfjord Crossing (the Egholm Line) is one of Denmark’s largest infrastructure projects in the coming years and forms a central part of the Infrastructure Plan 2035. A political agreement on the project was reached in spring 2024.
A new motorway and bridge connections west of Aalborg
The project includes an approximately 20 km long four-lane motorway connecting the E45 North Jutland Motorway in the south with the E39 Hirtshals Motorway in the north. The motorway will run west of Aalborg, cross the island of Egholm, and pass under the southern channel of the Limfjord (Sønderdyb) in a tunnel about 2 km long. Low bridge crossings will be constructed over the northern channel of the Limfjord (Nørredyb).
Along the stretch north of the Limfjord (between Nørredyb and Helledivej/Søvej), a total of 18 road bridges and wildlife crossings will be constructed, which SYSTRA will design. The project will be carried out in open countryside and also includes interchanges, access ramps, reconstruction of local roads and paths, as well as the installation of noise barriers.
Major bridge projects and wildlife crossings
The project includes both major and minor road bridges as well as a number of wildlife crossings that ensure free passage for animals and preservation of the area’s biodiversity.
SYSTRA’s deliverables for the section north of the Limfjord include:
- 6 new major road bridges (length approx. 15–150 m)
- 9 minor road bridges, primarily wildlife crossings (type B1 and B2)
- 2 medium-sized road bridges (wildlife crossings type A2, wet and dry)
- 1 new footbridge over the existing motorway
SYSTRA is responsible for, among other things, the project proposal and detailed design for tender documents, with an option for site supervision during the construction phase.
The Design phase is expected to begin in the second half of 2025, and the entire project is expected to be completed around 2031.
Et stærkt samarbejde
We are very proud to contribute to sustainable and traffic-safe solutions that support growth and mobility throughout North Jutland, and we look forward to continuing our strong collaboration with the Danish Road Directorate.
