Please don't stop building.  You taxpayers have come too far.  Not only should the project continue unabated, it should be lengthened and upgraded so that it makes a complete circle around Oahu.   Then, it should extend to every island in the Hawaiian islands chain.  After that, the next step of course is connecting Hawaii to the mainland and then to every country, island and atoll on earth.  Just keep on building and building and paying and paying into infinity.  Logic and common sense dictates that this be done.
