The Northern Harbour Link or Nordhavnsvej is a 3km-long bypass road being built between Nordhavn and Helsingørmotorvejen (Elsinore Highway) at the north of Copenhagen, Denmark. Consisting of a 620m-long tunnel and above ground roadway, the  project represents the biggest road infrastructure project in Copenhagen in the last 50 years.

The new road passing through the densely populated downtown district, two busy railway lines and major road intersections will improve the connection between the Helsingør motorway and the northern port area of Copenhagen.

Comprising two rectangular, two-lane tubes, the Nordhavnsvej tunnel is being built using the cut-and-cover method. The maximum depth of the tunnel is 22km below surface.

The tunnel formwork design is provided by PERI Group. The design includes two tunnel tubes each with 9.1m clear width, 25m-long concreting sections, tunnel-bottom slab, walls with large-sized panel formwork and creation of a passageway for onsite traffic.
