In order to advancing the Denmark’s Marselis Tunnel, Jacobs is due to deliver mechanical and electrical design and construction management services while collaborating with developer consultant Rambøll over the next decade.
The cut and cover method will be used for construction of this 1.8km-long tunnel and the Danish Road Directorate (Vejdirektoratet) project is currently in the planning and design. The scheduled date by authority for issuing a construction tender is spring 2027 and building works are going to commence in 2028. The project is planned for completion in 2036.
With the aim of connecting Aarhus Port to the E45 Østjyske motorway via Åhavevej, the tunnel will provide a faster, more direct and safer route and is placed in Aarhus, Denmark’s second-largest city and the country’s largest commercial port on the east coast of the Jutland peninsula.
The tunnel is a central component of Denmark’s Infrastructure Plan 2035 being delivered by the Danish Road Directorate in Aarhus.
According to Danish Road Directorate senior project manager Michael Schmidt Vosgerau: “Building a tunnel on one of the busiest access roads to Aarhus was a complex task.We will need international experience, because there are no similar projects like this that have been delivered before in Denmark.”
Jacobs senior vice-president Richard Sanderson said: “The Marselis Tunnel was a transformative investment in Denmark’s transport infrastructure, with the potential to unlock economic growth and enhance the quality of urban life.Our collaboration with Rambøll and the Danish Road Directorate reinforces Jacobs’ focus on advancing critical infrastructure projects that deliver sustainable, long-term benefits. By moving heavy traffic underground, the tunnel offers new possibilities for green spaces, safer streets, and a more vibrant city for residents and visitors.”
