WSDOT recently published its quarterly performance and accountability report, the Gray Notebook, and states that 92.1 percent of state-owned bridges measured by deck area are in fair or better condition. It is an improvement from 91.4 percent in 2010, and shows about a 700,000 square foot reduction in the bridges by deck area that were in poor condition.
