This document presents a case study of the controversy between freeway developers associated with the Washington State Highway Department and citizens of Montlake community, Seattle. The intent is to provide information to other neighborhood and community groups on successful citizen activism strategies. In the opening section, a chronology of events is presented to detail the process by which Montlake came to see the R.H. Thompson Expressway a threat. Information is presented on planning commission statements, highway department announcements, freeway-related bond issues, statements in favor of and opposed to the freeway, court hearings, and media coverage. The second section analyzes events discussed in the chronology, with emphasis on approaches within the anti-freeway effort which were particularly successful. Topics discussed include the mobilizing ideology of the anti-freeway coalition, techniques used to organize home-owners in the proposed freeway corridor, political characteristics of anti-freeway activists, and application of lessons learned in the Montlake experience to other citizen participation efforts. Appended materials include maps of Seattle and the Montlake community area, copies of newspaper clippings, special bulletins related to the controversy over freeway construction, and an artist's conception of the proposed freeway.
