Norwegian National Road 555

National Road 555 (Norwegian: Riksvei 555) is a 27.8 kilometers (17.3 mi) long national road which runs from the city center of Bergen to Kolltveit in Fjell, Norway.

In Bergen, the road has two branches, one two-lane from Nøstet via O.J. Brochs gate and on four-lane from Nygårdstangen, an the interchange with E16 and E39. The latter runs through the Nygård Tunnel before merging with the other branch and running across the six-lane Puddefjord Bridge. There, County Road 540 branches off into the Løvstakken Tunnel and County Road 582 branches off towards Laksevåg. 555 continues through the Damsgård Tunnel as a four-lane motorway, and at Nygård traffic towards the city center passes a toll collection and County Road 582 again intersects with 555. The motorway passes through the Lianakk Tunnel before having an interchange with County Road 557. In the future, this will be the a four-lane motorway heading south through the Knappe Tunnel. 555 continues through the Lyderhorn Tunnel before passing through an interchange at Loddefjord and then one at Storavatnet. At the latter, County Road 562 branches off towards Askøy, and 555 is reduced to a two-lane limited-access road. It passes through two short tunnels before having two interchanges at the Drotningsvik area. It then crosses Knarreviksundet on the Sotra Bridge, a suspension bridge. The road then enters Fjell and the island of Litlesotra. It then has two intersections at Knarrevik, one at Straume and crosses over to the island of Bildøy where it has two interchanges. It then crosses over to the island of Store Sotra and enters the Kolltveit Tunnel. National Road 555 terminates at a roundabout west of the tunnel, with Country Road 555 running south and Country Road 561 running north.
