For years, Seattle has used traffic counts on bridges as the chief gauge of overall traffic trends in the city. For 2010, traffic on Seattle bridges ticked upwards. But it was a modest increase, and it didn't even keep up with population growth. Over the longer term, traffic on bridges has fallen pretty dramatically---and the declines started in 2003-2004, long before the economy tanked.
