Transformative infrastructure project to boost economic growth and improve urban spaces

Jacobs (NYSE: J) has been selected to support the design and management of the Marselis Tunnel, a central component of Denmark’s Infrastructure Plan 2035 being delivered by the Danish Road Directorate in Aarhus.

Collaborating with developer consultant Rambøll over the next decade, Jacobs will leverage its global experience and project optimization strategies to deliver mechanical and electrical design and construction management services for the tunnel of this transformative infrastructure project in a high-density urban setting.

Jacobs Senior Vice President Richard Sanderson said: “The Marselis Tunnel is 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.”

The Marselis Tunnel project, expected to begin construction in 2028, is in the planning and design stage. Located in Aarhus, Denmark’s second-largest city and Denmark’s largest commercial port on the east coast of the Jutland peninsula, the tunnel aims to improve traffic flow between key transport hubs. Its purpose is to provide a faster, more direct and safer route linking Aarhus Port—a vital center for freight and logistics—to the E45 Østjyske Motorway via Åhavevej, a major arterial road. By rerouting traffic from Marselis Boulevard, a central city artery, the project also seeks to create a quieter, more environmentally friendly urban environment.

Danish Road Directorate Senior Project Manager Michael Schmidt Vosgerau said: “It is a complex task to build a tunnel on one of the busiest access roads to Aarhus. We will need international experience, because there are no similar projects like this that have been delivered before in Denmark.”

Rambøll Director of Transport-DK Asger Knudsen said: “Rambøll and our partners are proud and honored to be chosen for this important and complex task. We look forward to continuing our constructive and close collaboration with the Danish Road Directorate and to leveraging our combined experience to improve accessibility and enhance the urban space in Aarhus.”
