A ferry terminal in Lindberg Bay is extremely unlikely to ever be built. Port Authority, locally, and Customs/Immigration, federally, together would have to plan, fund and build it, it would usurp beachfront land which is more valuable as a resort development, would require permitting from Army Corps of Engineers, Coastal Zone Management, Legislative Approval and likely a bulkhead for sea conditions.
With Tortola Wharf existing downtown and another C&I building slated for Red Hook there would be little traffic anticipated from just airline transfers.
Taxi drivers do have a strong voting bloc but not as much political and financial influence except at the polls.
