Norwegian County Road 5627

Norwegian County Road 5627 () is a long road which crosses the Aurlandsfjellet mountains. The route was replaced by the long Lærdal Tunnel—the world's longest road tunnel. The barren mountain plateau offers views down on the Aurlandsfjord. It is designated a National Tourist Route in Norway.
Prior to the 2020 county merger, the road was called County Road 243, but after merging the counties, there were two county roads with the same number, so this one was changed.
