We are planning a Expressway renewal project in the following sections. For the replacement of floor slabs on bridges, traffic restrictions are expected to occur over a long period of time due to construction work, and traffic congestion is expected to occur. Please check the website, posters, leaflets, information boards, etc. for details such as construction details, traffic regulation details, and detour guidance.
Future construction schedule will be updated from time to time.
