However, in 1955 the Highway Department published a comprehensive freeway plan that anticipated new federal funding and initiated an era of unprecedented road construction in the growing city. In the early 1960s, localized opposition to the city's Interstate system failed to halt the completion of three major routes. Yet, politically savvy grassroots activists and a new generation of local leaders used the provisions of the National Environmental Policy Act and the Federal-Aid Highway Act of 1973 to successfully stop the construction of two freeways in the mid 1970s. Though favorable legislation and the efforts of local politicians were instrumental in thwarting the Highway Department's plans, this study will focus on the crucial role played by the citizens who waged an ideological battle against recalcitrant highway engineers for Portland's future. / Committee in Charge: Ellen Herman, Chair; Jeffrey Ostler; Matthew Dennis
