By building a tunnel directly from Arna to the city centre, this distance would be reduced to 8 kilometers (5.0 mi).
The Norwegian National Rail Administration is planning to expand the Ulriken Tunnel to double track, which would allow increased traffic on the whole Bergen Line and a 15-minute headway on the Bergen–Arna service.
[2] An alternative has been to build a branch of the Bergen Light Rail to Arna through its own tunnel through Ulrikken.
[3] Nygårdstangen acts as the main interchange in the city center, and distributes traffic between the city centre, traffic westwards along National Road 555 via the Nygård Tunnel, southwards along E39 along the Nygård Bridge and northwards along E39 and E16 through the Fløyfjell Tunnel.
It will be a 4 lane road east of the Ulriken mountain, bypassing the city Bergen, and including a shorter tunnel at Fjøsanger and eastwards.
