 Only the remote "Nesbø-Vassbygdi" region remains mostly undisturbed, if one ignores the strong reduction in the water flow in the "Aurlandselvi" and the visible stretch of highway between "Berdalstunnellen" (Berdal tunnel) and "Nesbøtunnellen" (Nesbø tunnel) visible in the hillside from the path at "Heimrebø".An all-weather road was built through the valley to support the hydropower development.This road also served the purpose of connecting eastern Norway with the western Norway, remaining open all winter and removing dependency upon ferries.
