WA-RD Reports
Over 700 Washington Research Documents (WA-RD), commonly known as WA-RD Reports, have been published. These documents summarize the research approach and findings of projects funded through WSDOT, and date back to 1969. Reports may be searched by key word, author, title, WA-RD number, or date. Abstracts are available for each document online, with a link to the full text. Print copies of most of the research reports are also available in the WSDOT Library collection. Search for a WA-RD Report.
