Despite the recommendation of a group of stakeholders to move forward with a surface/transit option and keep a deep-bore tunnel "on the table" (and despite the fact that voters rejected a tunnel, albeit a different one, in 2007), the city, state and county have reportedly all agreed to build a single deep-bore tunnel from King Street to Harrison Street downtown and to build a surface street for local traffic on the waterfront, according to a source. The tunnel was originally estimated at $3.5 billion, but that estimate has reportedly gone down as the design for the proposal has become more detailed. (The more detailed the design for a project, the less contingency is required; I have calls in to the city and state viaduct project managers to confirm the new cost estimate.) The good news, if there is any, is that the city and county alone will now be in charge of implementing the surface/transit part of the plan, which means Seattle will again have a say in redesigning its own waterfront. The bad news is that costs tend to balloon over time (particularly on projects at a very low level of design like this four-lane tunnel proposal, which would be one of the largest deep-bore tunnels in the world), the state has only allocated $2.8 billion to the project, and we're facing a nearly-$6 billion budget deficit.
More to come.
