The Transportation Series measures 2.0 cubic feet and dates from 1971 to 1990. The bulk of the records in this series document the I-90 corridor between I-5 and Bellevue, including the bridge over Lake Washington. Part of the regional transportation system, many parties were involved in planning the I-90 corridor and they did not always agree. Issues included lane configurations, funding, including state and federal funding, environmental issues, mass transit, and transit access. The records reflect both the length and the complexity of the decision-making process. The actions of the Transportation Committee, of which Paul Kraabel was either vice chair or a member, are well documented with respect to the I-90 issues. The Puget Sound Council of Governments acted in an oversight capacity and because several Councilmembers were on PSCOG, including Paul Kraabel, Jeanette Williams, Phyllis Lamphere, and George Benson, the actions of this organization are also well documented. Other organizations and individuals represented in the series include METRO, the City of Mercer Island, Mayor Royer, Margaret Tunks, and Jerry Schneider.
