The Seoul-Yangpyeong Expressway project, connecting Hanam City to Yangpyeong County, was initially included in the 2017 First Expressway Construction Plan. Its purpose is to strengthen the main transit function of the eastern capital region and promote balanced regional development, especially in northern Gwangju City and Yangpyeong County. The project gained momentum in December 2018 when it was incorporated into the Greater Hanam Gyosan New Town transportation plan. After passing a preliminary feasibility study in April 2021, subsequent feasibility and strategic environmental impact assessments began in 2022.
Local residents, municipalities, and political stakeholders have consistently advocated for the expressway’s swift resumption, citing growing traffic congestion and the region’s development aspirations. The expressway is expected to alleviate heavy weekday commuter and weekend tourist traffic on National Route 6 and the Capital Region’s First Ring Road. The upcoming occupancy of Gyosan New Town in 2029 further underscores the urgency of this infrastructure project. The government aims to resolve the inconvenience caused by construction delays and fulfill longstanding local demands.
The project was halted in July 2023 following a route change from Yangseo-myeon to Gangsang-myeon, which became subject to a special investigation. Nearly three years of suspension ensued. Under President Lee Jae-myung’s directive, the government will resume the project in the first half of 2026. The Ministry of Planning and Budget will prepare funding support, commission a new feasibility study, and select the optimal route for residents and future generations. Construction is scheduled to begin by the end of 2029.
Frequently asked questions include: Why was the project suspended? The halt was due to a route change and subsequent special investigation in mid-2023. What are the next steps? The government will secure funding, conduct a new feasibility study, and finalize the route before construction starts in 2029. How will this benefit residents? The expressway will ease traffic congestion and support balanced regional development. When will construction begin? The target is late 2029, following completion of preparatory procedures.
The government’s decision to restart the Seoul-Yangpyeong Expressway project is a direct response to persistent local demands and worsening traffic congestion. By aligning the construction timeline with the expected occupancy of Gyosan New Town, authorities are addressing both immediate and future transit needs. The emphasis on transparent funding, feasibility studies, and route selection reflects a commitment to resolving past controversies and ensuring balanced regional development. This approach is likely to improve public satisfaction and support sustainable infrastructure growth.
