This traffic control is a measure for installing the girder of the newly constructed bridge crossing National Road No. 3, with two out of three lanes in both directions being closed. Additionally, a full closure of all three lanes in both directions will occur twice for 15 minutes each (from midnight to 12:15 AM and from 2:30 AM to 2:45 AM) to accommodate the girder placement work.


Since this section usually experiences heavy traffic, Gwangju City plans to carry out the construction during nighttime hours and, with the cooperation of the police station and deployment of sign cars, will encourage vehicles to slow down to prevent accidents and minimize inconvenience to citizens.


A Gwangju City official stated, “This construction is an unavoidable measure to alleviate severe traffic congestion in the Taejeon district and on National Roads No. 43 and 45. We ask for the active cooperation of citizens and safe driving.”



Meanwhile, the ramp construction project for the Seongnam?Janghowon expressway involves creating an entrance and exit ramp with a total length of 1.856 km (including a 65 m crossing bridge) that directly connects the Taejeon district to National Road No. 3 (Seongnam?Janghowon) via Gobul-ro and Jung-ro 1-17. The project is scheduled for completion and full opening in January 2026.
