I can't remember exactly why but there were numerous safety concerns with it so it never made the final cut. I think it was one of the options a long time ago when they had open submissions for ideas, but due to safety concerns it was tabled in favor of the three options that are currently being bandied about.

Essentially a tunnel with no roof. Crossing roads would become overpasses. This would be a lot cheaper than a complete tunnel, preserve the views, abate the noise, be safer for earthquakes or flood, and wouldn't require the destruction of Alaskan Way during construction. Just my $0.02. There is an undiscussed alternative to a tunnel or a new viaduct. 99 could be replaced with a sunken roadway on the footprint of the existing viaduct.
