Something really bad didn’t happen when Seattle closed the Alaskan Way Viaduct to traffic, reported to carry 110,000 vehicles a day.  From Crosscut:



In news coverage leading up to “Viadeath 2016”, Inrix provide the official data forecasts for Seattle’s traffic snarls. The company predicted commute times would increase by 50 percent …

But in an e-mail exchange with Crosscut, a representative speaking on behalf of Inrix backpedaled on their initial predictions, saying that, “According to INRIX’s analysis, commute times have not dramatically increased and several of the major routes into the City have been only moderately affected.” …

On I-5 travel time has increased by about five minutes, and rush hour has shifted toward 6 AM as people allow themselves more time to get into work. The same goes for the West Seattle bridge, on which travel times have jumped about five minutes. On I-90 Westbound, commutes have only increased by between three and five minutes. And on 520, traffic’s about normal.

Obvious question: Why is Washington spending over $4 billion to build a bored tunnel when demand management, a new surface street and better transit could have done the job?
