The Seoul city government will invest 7.3 trillion won to expand transportation infrastructure in the southwestern area and turn Magok, Onsu Industrial Complex, and the Seoul Digital Industrial Complex (G Valley) into hubs for Mirae Industries.
Oh Se-hoon, the Seoul mayor, said on the 5th that the city will push the SuNAM area grand overhaul 2.0 project. At a press briefing the same day, Oh said, "Along with the northern area, we will accelerate Seoul's growth through the second phase of the non-Gangnam area grand overhaul, SuNAM area grand overhaul 2.0, which will be the two pillars of balanced development in Seoul." On the 19th, Oh announced the Again, Northern Heyday 2.0 project.
SuNAM area grand overhaul 2.0 follows SuNAM area grand overhaul 1.0 announced two years ago, with key strategies including ▲ establishing a fully connected transportation system ▲ creating advanced industry hubs ▲ rapid supply of dwellings ▲ expanding green-axis linkages. The total project cost is 7.3 trillion won.
The city will invest about 5.5 trillion won to expand transportation infrastructure, including building out rail networks and opening or widening roads. The city will put the Nambu Beltway and National Assembly-daero underground and widen the West Arterial Road to five lanes. The Gangnam Circular Road will be extended to the Nambu Beltway via the Sillim-Bongcheon Tunnel. This will cut travel time from Gangnam to Gangseo from 70 minutes to 40 minutes.
It will also expedite four major rail lines: the Gangbuk Transverse Line, Mok-dong Line, Seobu Line, and Nangok Line. The Gangbuk Transverse Line and Mok-dong Line did not pass the preliminary feasibility study by the Ministry of Economy and Finance, and the Nangok Line is undergoing a preliminary feasibility review. The Seobu Line, being pursued as a private investment project, is adrift after a construction company's withdrawal. The city plans to diversify business methods and improve the preliminary feasibility system, aiming to start construction of the Seobu Line in 2029 and complete it in 2034.
The city will reorganize Magok, the Onsu Industrial Complex, and G Valley into spaces where advanced industries and quality jobs coexist. It will convert reserved land in Magok into mixed-use sites to attract cultural and convenience facilities and develop it as a physical artificial intelligence (AI) industry hub. For G Valley, it will promote mixed-use development in special planning (eligible) zones such as Kyohaksa and Mario Outlet. The Onsu Industrial Complex will revise its district unit plan to expand basic and support facilities.
It will also innovate semi-industrial zones. On the former rugby field site at Onsu Station, it will establish a Technical Talent Academy to provide vocational training for the robotics industry. In Gocheok-dong, it will create Seoul Tech Space, a facility with advanced manufacturing and data analysis functions. The site of the Seobu Truck Terminal in Sinjeong-dong will undergo mixed-use development through 1.94 trillion won in private investment. In addition, it will pursue high-density development of the Dong-Yeouido parking lot site, development of the Geumcheon Air Force base, and improvements to the Jungang Steel Wholesale Market in Siheung-dong.
The city also plans to accelerate the supply of dwellings. Through the Rapid Integrated Planning (36 sites), Moa Town (37 sites), and Moa Dwellings (11,996 units), it will break ground on about 73,000 dwellings by 2030. It will build 580 family-friendly dwellings on the Dangsan public parking lot and Nambu Women's Development Center sites to ease housing problems and caregiving burdens. It will also support the reconstruction procedures for the Gayang and Deungchon housing development districts.
It will increase infrastructure by creating multi-purpose comprehensive sports facilities and complex cultural facilities at the Seobu Truck Terminal and Mokdong Stadium and detention basin. It will attract more than about 150 billion won in private investment to the public parking lots in Gaebong-dong and Gaehwasan Station to expand public facilities such as administrative complexes and a senior town without public spending. It will also focus on securing green space by creating an urban street forest across the G Valley area. The city will build the Seoul Green Path, which linearly connects fragmented forests, parks, and streams, to a length of 48.4 kilometers by 2027.
