The elevated bridge damaged in the Kumamoto earthquake will be repaired using a continuous truss system.

The Nankin First Bridge on the Nankin Expressway in the southern Kyushu region is damaged due to the 2026 earthquake, and it has decided to adopt a continuous truss repair plan, with an expected opening in late 2028. The design plan has already started, and the work will be carried out in stages, including the removal of the upper structure, reinforcement of the bridge piers, and installation of new trusses.

Why it matters. The repair work will affect the traffic on the southern Kyushu Expressway, and it is expected to resume operation by the end of 2028, contributing to the recovery of local transportation.
