Millau Viaduct crosses the Tarn Gorge and is one of the highest bridges in the world. More than 20 years after its completion, it still holds the record for the highest pier in the world. It is a shining pearl in the history of human architecture. In this study, the construction processes and strategies of Millau Viaduct are introduced in detail. Results show that after the concrete pier was poured, the bridge deck was pushed forward by applying the jacking from the tail then completed the construction of the long-span bridge. In order to reduce the impact of wind during construction, the construction team improved the construction accuracy by optimizing the bridge model and using satellite positioning. Combined with understanding and perception of the high span and high-risk construction projects such as Millau Viaduct, some methods are put forward to improve the construction technology. These construction methods could be adopted in the future to reduce the risks associated with the project.
