The road construction project between Jeongnim-dong and Sajeonggyo in Seo-gu, Daejeon, is currently underway with a budget of 101.74 billion won (40.87 billion won from the national government and 60.897 billion won from the city), aiming for completion in January 2028.

The city is actively pursuing the tunnel construction (total length: 980 meters), which is the core section connecting Jeongnim-dong in Seo-gu and Anyoung-dong in Jung-gu.

The road construction between Jeongnim Middle School and Sajeonggyo is being promoted to alleviate traffic congestion on National Road No. 4, Gyebaek-ro (from Gwanjeo-dong to Seodaejeon Four-way Intersection). The new road will have a total length of 2.4 kilometers (including one tunnel and three bridges), a width of 20 meters, and four lanes for two-way traffic.

Since March, the city has begun constructing the tunnel entrance, installing auxiliary facilities such as the upper retaining wall, concrete manufacturing equipment, and wastewater treatment facilities for tunnel excavation. Full-scale tunnel excavation has been underway since mid-September.

Jeon Jonghyun, Director of the Construction Management Headquarters, stated, "Once the road opens, it will be linked with the Gyebaek-ro bypass construction section (from Gwanjeo-dong to Jeongnim-dong in Seo-gu), establishing an outer ring road network for downtown Daejeon. This is expected to significantly contribute to traffic dispersion and balanced regional development."
