As a national strategic project in Indonesia, Sungai Tondano Bridge is an experimental project for exploring new technologies by the Indonesian bridge committee. During the construction, CSCEC builders faced difficulties and made bold innovations under the harsh environment with complex geological conditions. Through standardized management and fine construction, the project is completed and opened to traffic on schedule, showing a brand-new image and strong strength of CSCEC.

The Manado-Bitung Expressway in Indonesia is the first one that starts construction among the six national strategic projects launched in North Sulawesi, Indonesia, and it is also an overseas key project in response to China's Belt and Road Initiative, which has received much attention. The expressway connects North Sulawesi and Manado, a tourist resort, and Bitung port. After opening to traffic, the driving time is shortened from 120 minutes to 30 minutes, which has greatly saved the time between the two cities, relieved the transportation pressure, made it possible for the Bitung Industrial Park to be opened soon, and also provided convenience for the development of local tourism.
