Portland’s I-5 Expansion: Evaluating the Environmental and Cultural Impact of ODOT’s Rose Quarter Improvement Plan

Abstract

To this day highway expansion remains one of the primary techniques employed to combat urban automobile congestion during peak hours. This paper examines the cultural and environmental shortcomings of Portland, Oregon's I-5 highway expansion project. Research for this paper primarily cites existing academic studies relating to highway expansion, Portland's complicated relationship with urban renewal, and highway expansion alternatives. The evidence suggests that Oregon's expansion project would have less than optimal impact and the resources could be used better elsewhere.
