Urban transportation systems are increasingly challenged by congestion, sustainability concerns, and limited space for expanding traditional infrastructure. As cities continue to grow, there is an increasing interest in innovative transportation systems that can enhance mobility while minimizing environmental impacts. This study aimed to evaluate the feasibility of implementing an Urban Aerial Gondola (UAG) system over the University of Washington (UW) campus as a sustainable transportation solution. Through an internship with the Seattle Subway Foundation (SeaSub), research was conducted using literature reviews, professional interviews, public outreach events, and a comprehensive survey distributed to UW students, faculty, and staff. In addition, the Portland Aerial Tram in Portland, Oregon, was studied as a primary example of an urban aerial transit system in operation to observe practical application. Results indicate that UAG systems may offer significant benefits, including reduced travel times, lower environmental impacts, and improved navigation across challenging urban terrain, without requiring extensive ground-level infrastructure. However, research also identified critical challenges related to funding models, air rights, stakeholder coordination, and mixed public perception. Survey responses demonstrated interest in innovative transportation alternatives while also revealing significant concerns regarding practicality and cost. These findings suggest that urban aerial gondolas could serve as a valuable supplemental transportation option in dense urban environments if supported by effective planning and community engagement. Ultimately, this research highlights how diversifying transit modes is essential for fostering more resilient city infrastructure in a rapidly changing climate.
