"Whether they can get the Legislature -- specifically, House Speaker Frank Chopp -- to endorse the most expensive option for replacing the vital Seattle arterial remains to be seen."

"The last time the viaduct battle came to a head, Chopp, D-Seattle, vigorously opposed anything but an above-ground replacement. He is credited with killing the tunnel plan the last time around."

"Since that time, he has invested energy designing and promoting an above-the-ground replacement that would have included a throughway and a shopping center -- all capped with a waterfront park."

"On Monday, Seattle Deputy Mayor Tim Ceis confirmed that a consensus had been reached to build a deep-bore tunnel, with an estimated cost of more than $4 billion."
