Headline and Article from the AP Wire:
If this proposal makes on to the November ? ballot, this vote will be worth following.Their proposal to replace the viaduct with a major tunnel has critics pointing to Boston, where another ambitious highway project stampeded past deadlines and cost estimates.
Tunnel supporters dismiss such dire predictions, and believe they could gain a crucial stamp of public approval if the City Council agrees to hold a citywide vote on the tunnel this fall.
Seattle and Boston have the same yearning: to reclaim the views and property values scarred by Cold War-era elevated highways. Boston built a series of tunnels at a cost of $14.6 billion, the most expensive highway project in U.S. history.
"The Big Dig now has become almost a mythical thing in the American public works landscape, for good and for ill," MacDonald said.
The viaduct definitely is a liability. Built in the 1950s, it was damaged in a 6.8-magnitude earthquake in 2001, and engineers warn it could collapse in another temblor.

Being twin decked remember what happened on Oakland, CA twin decked highway in the World Series Earthquake
(1989), reasonable to replace it but according to the article the controlling factor is the volume of traffic.
This also fits the thread on urban waterfronts.
The Alaskan Way Viaduct shuttles more than 100,000 automobiles each day on twin concrete decks that soar above the sparkling waterfront. The highway is also drab, rickety and outdated, and Mayor Greg Nickels and his allies want to bury it.
Nickels' more modest plan in Seattle would consist of a single tunnel topped by an urban park and commercial zone.
