Combining a new tunnel with special-purpose guided buses to avoid the southern detour to Te Anau on the route from Queenstown to Milford Sound, this proposal would provide the shortest possible route. Proposed by a group of South Island businessmen who also have an interest in some of the tourist operations in the Sound, this scheme would make use of the fact that the Hollyford Valley, where the existing road to Milford Sound from Te Anau turns west up to Homer Tunnel, is only a few dozen kilometres away from the Routeburn Valley (of Routeburn Track fame), in turn easily reached by existing roads.
