Orphan Road

I didn't live in Seattle when Sound Transit planned the route of the light rail, so stop me if this has already been debated to death. Also, I know it's far too late to change anything. I'm just curious.

Can someone tell me why, exactly, Link takes it's expensive and circuitus path? Considering it will take as long (or longer) as it currently does via bus to get from downtown to the airport, this would not seem like a great idea.

One would think a straight line would be the easiest, cheapest, and fastest route. This would take us through some industrial areas, which would seem to have inexpensive land. It would also drive by Boeing Field, which could be useful if it ever runs as a commercial airport. Plus it seems like there would have been little/no boring reqired.

Yes, the route drives through a few communities, but this seems like a reason to not put light rail there - you end up stopping at stoplights. Building communities around transit seems like a much better idea.

I imagine a strong difference between city-based transit, that tries to conform to neighborhoods, and regional transit, that should be built for speed. This is clearly regional transit, but seems to be designed as city transit.
