Transportation Asset Management Plan

The Washington State Department of Transportation (WSDOT) has the challenging task of managing a complex transportation network that includes the largest ferry system in the U.S., the world’s three longest floating bridges, nearly 18,700 lane miles of state highways, and over 3,800 bridges and structures. This network reflects the vibrant and diverse citizens of Washington State and serves to connect communities and families while supporting the state’s world class economy.

Washington state has experienced significant growth in recent years, placing an increased strain on our aging infrastructure along with an added desire for capacity. Recognizing funding is a finite resource, asset management is a critical practice to ensure WSDOT’s investments return the highest amount of benefit at the least amount of cost. Asset management is a fundamental component of the agency’s Practical Solutions framework which balances investments to achieve and sustain a State of Good Repair for our existing transportation network against strategic system expansions that meet the need of added demand.
