Yongin City, led by Mayor Lee Sang-il, announced that the improvement project for National Route 57 (from Mapyeong to Wonsam) has passed the preliminary feasibility study conducted by the Ministry of Economy and Finance on August 27.


On August 26, the 6th Financial Project Evaluation Committee reviewed and approved the feasibility study, allowing the project to be included in the '6th National and Local Road Construction 5-Year Plan.' The Ministry of Land, Infrastructure and Transport is expected to finalize and announce the '6th National and Local Road Construction Plan' after October.


The National Route 57 improvement project aims to enhance the road alignment and traffic facilities over approximately 12.3 kilometers, from the Yongin Arts and Science College intersection in Cheoin-gu to the Yongin Semiconductor Cluster industrial complex in Wonsam-myeon. The total project cost is estimated at 221.9 billion won.


This project includes the construction of a tunnel at Gobdeung Pass along Route 57. The city plans to improve the road alignment by creating a new tunnel in the steep and narrow 2.88 km section.


Additionally, pedestrian safety measures will be implemented, including the installation of sidewalks and the creation of left-turn lanes for vehicles entering nearby villages.


Mayor Lee stated, "National Route 57 is a crucial transportation infrastructure connecting the city center with the Yongin Semiconductor Cluster in Wonsam, home to SK Hynix. The new Gobdeung Pass tunnel will improve a hazardous road section and enhance connectivity with National Route 45, significantly increasing convenience for citizens through the installation of sidewalks and left-turn lanes."


During the Financial Project Evaluation Committee meeting, the 'National Route 23 (Anseong Daedeok to Yongin Namsa) Expansion Project' also passed its preliminary feasibility study. This project aims to expand a 1.7 km section from the Jinmok Intersection in Namsa-eup, which has remained a two-lane road, to a four-lane road, addressing the bottleneck issue.


The road leading to Wonsam-myeon is being expanded to enhance access to the SK Yongin Semiconductor Cluster, with a 1.88 km section of Bogeawon-Samro having opened in May.
