Study Funded By Tunnel Supporters Supports Tunnel

Would building a tunnel to replace the Alaskan Way Viaduct cost insane amounts of money? Yes. But wait, according to a new "study," the super-amazing fantastic tunnel of love would return that all of that expense (and more!) back to the city . Just like magic!

Replacing the Alaskan Way Viaduct with a tunnel instead of a new elevated highway is well worth the extra cost, according to a study released Wednesday by a Seattle business group.

Tunnel opponents quickly criticized the Downtown Seattle Association study, and some were not even willing to concede that the current viaduct needs replacing. A state Transportation Department official warned that the project would soon stall without a decision on which option to pursue.

A tunnel along the downtown Seattle waterfront would cost $3 billion to $3.6 billion — at least $1 billion more than a new viaduct there, according to state estimates. But it would increase area property values by $450 million, stimulate $1 billion to $2 billion in development on "severely underbuilt" land and spur an extra $162 million to $325 million a year in tourism, according to the study, which economist Glenn Pascall presented at the Bell Harbor International Conference Center.

The association, which supports a tunnel, hired Pascall to review the effect of building one. Pointing to benefits that resulted from tearing down the Embarcadero Freeway in San Francisco and even from the construction of the notorious Big Dig in Boston, he said a tunnel would "create a magnet event."

In response, the No Tunnel Alliance noted that the study used the low end of the state's estimated cost difference between a tunnel and a viaduct and said it did not account for cost overruns and delays that some have said would be more likely with a tunnel. The group also questioned the study's conclusions regarding increases in property values and tourism, said a lack of tunnel exits downtown would increase congestion and harm businesses and worried about delays from city efforts to find the extra money for the tunnel.

So there you have it. Now we know that a tunnel would be worth the insane cost, because a study funded by the tunnel-loving Downtown Seattle Association says so.

Bah. I still want a bridge over Elliot Bay.
