Danish engineers have been in town, researching the feasability of replacing the Montlake section of Highway 520 with a tunnel. Traffic, with its noise and unsightly bulk, would magically disappear under the ground, leaving upscale real estate in the area even more valuable.
I actually like the idea. If we must have more highway lanes from/to the burbs, might as well put ’em where we don’t have to see ’em.
Of course, there’s always the little bugger of what it would cost…
