look, there is no other alternative currently or in the near future that the state will be providing another freeway to alleviate traffic from the westside to Honolulu.  in the meantime with the new developments in east Kapolei and westridge, the traffic will get worse.  rail will help with the traffic by providing a traffic free alternative to driving,  further the county and state knows that building affordable housing along the rail route is a must, as it will reduce the need for additional cars and allow for residents to use rail as their primary transportation mode, eliminating the need for owning a car.  hence, there are plans for building affordable housing, malls, schools, hospitals, etc..  of course it will not occur overnight but over time.  but you have to start sometime and somewhere.  to wait another 50 years is folly.  further, all housing developments, etc. are built by private developers and there is nothing wrong with that.  gov't cannot do that.
