Reports of a cockroach infestation have surfaced at Seoullo 7017, an elevated pedestrian park in Seoul [1].

The situation raises concerns regarding the management of public infrastructure and the effectiveness of urban sanitation in high-traffic tourist areas. Visitors and critics point to the infestation as a sign of failing maintenance in a landmark designed to revitalize the city center.

Seoul City officials and the management of Seoullo 7017 have faced scrutiny following sightings of the insects throughout June 2026 [3]. The reports suggest that the infestation is the result of inadequate pest-control measures and rising costs associated with maintaining the elevated structure [1].

The park was created by transforming an old overpass into a green space at a cost of 60 billion won [1]. Since its opening, the cumulative expenses for operation and maintenance have exceeded 25 billion won [3].

There is a discrepancy between official statements and reported conditions. Seoul City said its pest control efforts are working [4]. However, other reports describe the situation as a cockroach crisis [2].

The elevated nature of the park creates unique challenges for pest management, as the structure's design can trap moisture, and debris. Despite the significant financial investment in the project, the current sightings suggest a gap between the city's maintenance budget and the actual environmental needs of the site [3].

“Seoullo 7017 is facing a cockroach crisis.”

The conflict between city reports and public sightings highlights a tension in urban governance: the struggle to maintain 'prestige' infrastructure once the initial construction phase ends. When maintenance costs rise, the gap between official narratives of success and the physical reality of decay—such as pest infestations—often widens, potentially impacting tourism and public trust in city management.
