Portland's bridges are among the busiest bicycle routes in the city. The Bureau of Transportation has conducted bicycle counts for the Broadway Bridge, Steel Bridge, Burnside Bridge and Hawthorne Bridge since 1991. This map displays data from the bicycle counts in order to compare the ridership levels between bridges, show growth in ridership over the past two decades and to show changes between automobile and bicycle use of the bridges.

In addition to the data-driven characteristics of the graphic, I also created a series of logos for each bridge. They are incorporated into the poster and also produced as buttons.
