Seongnam City to Hold Public Inspection for Seopangyo Connecting Road Project... Anticipated Improvement in Pangyo Traffic

Public Opinion Hearing to Begin on April 27
Targeting Project Implementation Approval by August
Plan to Expand Road Use to More Vehicle Types and Pedestrians

Seongnam City in Gyeonggi Province (Mayor: Shin Sang-jin) announced on April 24 that it will conduct a public inspection and announcement on April 27 to gather residents' opinions regarding the 'Seopangyo Connecting Road' construction project. The project aims to alleviate traffic congestion in the area surrounding the 2nd Pangyo Techno Valley and to improve convenience of movement by linking severed road networks.

After the public inspection procedure, the city plans to proceed with deliberation by the Urban Planning Committee, consult with relevant agencies such as the Ministry of Land, Infrastructure and Transport, and accept applications for project implementation approval until August once these steps are completed.

The road in question will run for a total length of 271 meters through the 2nd Pangyo Techno Valley area, with 238 meters of that section constructed as an underground road. In 2016, the Ministry of Land, Infrastructure and Transport decided to pursue the project as part of traffic improvement measures for the 2nd Pangyo Techno Valley, and Korea Land & Housing Corporation (LH) is currently carrying out the project.

Progress has been challenging due to structural factors, such as the project section needing to pass under the Outer Ring Road, the 2nd Gyeongin Expressway, and the Pangyo Interchange ramp, along with concerns about increased traffic volume and noise. These issues led to differences of opinion among residents. According to Seongnam City, from 2017 to the present, a total of 94 complaints for and against the project have been received.

To address traffic problems in the 2nd and 3rd Pangyo Techno Valley areas, the city has operated a dedicated task force since October 2024, collecting resident feedback on transportation improvement plans—including the Seopangyo Connecting Road—and continuing consultations with Korea Land & Housing Corporation (LH).

Notably, in December 2024, the Ministry of Land, Infrastructure and Transport transferred permitting authority to Seongnam City to expedite the project, enabling the city to participate more actively in all aspects of the project.

Subsequently, in response to the Korea Land & Housing Corporation (LH)'s project implementation approval application submitted in September 2025, the city provided supplementary opinions such as widening the road and expanding its use. With LH accepting these suggestions, an application to initiate (amend) the urban management plan was submitted on April 3.

The main changes include expanding the road—originally planned for passenger cars only—so that large vehicles (such as route buses), passenger cars, bicycles, and pedestrians can all use it.

Seongnam City intends to proceed with all administrative procedures without delay while, after the opening, thoroughly promoting the project by comprehensively considering improvements in traffic flow, resident safety, and the local living environment.
