Connecting downtown Seattle and downtown Bellevue is a grand idea—a far better idea than connecting the airport to downtown. Both are major centers of employment. My understanding is that there are some technical / engineering challenges to running light rail across via I-90, but smarter people than I seem to think that they are surmountable. In principle, I think that light rail is just another transit technology, and an expensive one at that. BRT could easily be done in lieu of light rail. In practice, however, Seattle seems to do a terrible job at BRT. Rapid Ride got watered down to the point where I simply call it "bus red transit." So, maybe we can't actually build good quality BRT, and we need the huge capital expenditure of light rail to do it right.
