내용

Busan Metropolitan City (Mayor Park Heong-joon) announced that it will hold the groundbreaking ceremony for the “Construction of the Northern Access Road to the Busan-Jinhae Free Economic Zone (Jangnakdaegyo Bridge)” at 10:30 a.m. today (23) at Eco Delta City in Gangseo-gu (the terminus area of the Jangnakdaegyo Bridge project).

The ceremony is expected to be attended by around 250 people, including Vice Mayor for Future Innovation Seong Heui-yeob, Busan Metropolitan City Council Vice Chair Lee Jong-hwan, district heads, city council members, district council members, and local residents, to celebrate the start of construction.

The event will run for about 40 minutes in the following order: National Ceremony, introduction of distinguished guests, report on project progress, commemorative address, congratulatory remarks, and a ceremonial performance to mark the groundbreaking.

The Jangnakdaegyo Bridge construction project will build a 1.53-kilometer road (two-way, six lanes) from Saenggok-dong, Gangseo-gu (Busan-Jinhae Free Economic Zone) to Myeongji-dong (Eco Delta City).

Section: Saenggok-dong, Gangseo-gu (Busan-Jinhae Free Economic Zone) to Myeongji-dong (Eco Delta City)
Scale: Road construction L=1.53 km (bridge L=1.03 km), B=24.5–27.1 m (six lanes, two-way)
Total project cost: KRW 163.6 billion (national KRW 80.0 billion, city KRW 83.6 billion)
Project period: 2018–2030

Since 2018, the City has promoted the Jangnakdaegyo Bridge project to build a road network that meets transportation demand in western Busan and alleviates congestion on existing bridges crossing the Nakdonggang River.

Although there were challenges during consultations with relevant agencies due to concerns such as potential environmental impacts from constructing a new river-crossing bridge, the City finalized major administrative procedures last year. Following the earlier commencements of the Daejeodaegyo Bridge and the Eomgungdaegyo Bridge projects, this groundbreaking ceremony marks the beginning of full-scale construction.

The project was incorporated into the Busan-Jinhae Free Economic Zone development plan in April 2015, and in December 2017 it passed the preliminary feasibility study conducted by the Ministry of Economy and Finance, thereby securing project feasibility.

To minimize environmental impacts from bridge construction, the City completed key administrative procedures through communication with local residents, environmental organizations, and the government, including a small-scale environmental impact assessment (September 2023) and approval for alteration of a national heritage site (October 2024). It then completed the detailed design in December 2024.

With extensive cooperation from relevant agencies, including the Ministry of Trade, Industry and Energy and the Ministry of Environment, construction began in December 2025. With this groundbreaking ceremony as a starting point, the project will proceed in earnest, with completion scheduled for the end of 2030.

Beginning with this ceremony, the City will make every effort to ensure the project is carried out smoothly through its completion in 2030. In particular, even during construction, it will pursue bridge construction that coexists with nature by maintaining ongoing consultation and communication with relevant agencies, experts, and environmental organizations.

Mayor Park Heong-joon said, “The Jangnakdaegyo Bridge is a core transport infrastructure of the third east–west corridor, passing through Eco Delta City and connecting to the Eomgungdaegyo Bridge, the Seunghak Tunnel, and the North Port Hinterland Road.” He added, “It is expected to significantly improve logistics transport and traffic flow in western Busan, promote balanced regional development, and strengthen connections among new growth hubs such as Eco Delta City—delivering tangible transportation improvements that residents can directly experience.”

He continued, “This project will help accelerate balanced development in Gangseo-gu and western Busan and serve as a key gateway facility for east–west integration as Busan takes a leap forward toward becoming a global hub city. We will do our utmost to ensure the project proceeds without disruption through completion so that residents can use it safely and conveniently.”
