Located on the Vestfold Line, the tunnel was built as part of the 14.3-kilometer (8.9 mi) double-track high-speed segment from Holm to Nykirke. The new Holmestrand Station is located inside the mountain in the middle of the tunnel. The total cost of the project was estimated to be 6.6 billion Norwegian Kroner upon completion. The new tunnel reduces traveling time on the Vestfold Line by five minutes.
