RCW 47.01.408
Finding-2008 c 270: "The legislature finds that the replacement of the vulnerable state route number 520 bridge is a matter of urgency for the safety of Washington's traveling public and the needs of the transportation system in central Puget Sound. The state route number 520 bridge is forty-four years old and has a useful remaining life of between thirteen and eighteen years. While one hundred fifteen thousand vehicles travel on the bridge each day, there is an ever present likelihood that wind or an earthquake could suddenly destroy the bridge or render it unusable. Therefore, the state must develop a comprehensive approach to fund a state route number 520 bridge replacement to be constructed by 2018." [ 2008 c 270 s 1.]
