As part of County Road 64, the tunnel would replace the Åfarnes–Sølsnes Ferry, and allow Romsdal ferry-free access to Eastern Norway, as well as connect Molde and Rauma.
If the branch is built, it would replace the Molde–Sekken Ferry, giving the island a fixed link.
The project was originally planned to be self-financed as a toll road, without receiving other state grants than the subsidies which would otherwise have been given to the ferry.
Should the Langfjord Tunnel need public grants, with today's funding level money would not be allocated until the late 2020s.
This will increase the income for the toll road, as they receive the money which would otherwise be used for the ferry.
