The Washington State Department of Transportation (WSDOT or WashDOT, both /ˈwɒʃdɒt/) is a governmental agency that constructs, maintains, and regulates the use of transportation infrastructure in the U.S. state of Washington. Established in 1905, it is led by a secretary and overseen by the governor. WSDOT is responsible for more than 20,000 lane-miles of roadway,[3] nearly 3,000 vehicular bridges and 524 other structures. This infrastructure includes rail lines, state highways, state ferries (considered part of the highway system) and state airports.[4]
