If your main concern is traffic, you should be anti-rail since it has been said by HART and in the AA that rail will not alleviate traffic now or in the future.  $10 billion to not reduce, but increase, traffic.

What to do with current guideway?  Shouldn't the pro-rail contingent come up with that solution since you all supported this ill-conceived project in the first place?  Take some responsibility for your decision and spend the time to think of a solution.  Everything the anti-rail side has come to pass and now you ask us what to do about your project?  lol  For goodness sake, you couldn't even think of a rail benefit before building the guideway.

That being said, the columns should be re-engineered for a bus flyway.  Getting to downtown in 25-30 minutes every day will certainly increase express bus ridership and DECREASE freeway traffic.  Or put a dome on and make it a homeless detention area whereby they can't leave unless willing to go to a shelter.  Or examine mag-lev.
