It's safe to say Seattle will try very hard to make the rest of us pay for their mistakes. IIRC the people of Seattle and their government did not exactly push hard for the current plan? There was a referendum in which both the tunnel option and reinforcing the viaduct did not garner popular support, although reinforcement got more votes than a tunnel. I think in this case "it's safe to say everyone is going to have to pay for everyone's mistake" is more fair. And certainly SR99 has impact outside Seattle, since Seattle is a huge part of the WA economy and basically anything that has impact in Seattle, has impact in WA.
