spending $8 billions for such a skyway?  foolish.  another $2 billion and it can be completed as planned and have a multi-model transportation system and the route as development for TODs (affordable housing).  Really, $8 billion for a bike and jogging path?  nonsensical.  sure new technology may help with traffic, but with not new roads or highways planned in the foreseeable future, the highways and roads will only become more congested as time goes by with increased population, especially from the westside.  cars have been the preferred mode of transportation but with increase population and congestion, a new alternative that would provide meaningful action is necessary.  hence, the use of cars must be discouraged and rail is the best alternative.  people living along the route will not need more than one car per family.  we cannot effectively limit the number of cars and people so there needs to be alternatives to voluntarily encourage people to reduce dependence on cars.
