How long is the Hong Kong-Zhuhai-Macao Bridge?

As far as I know, the Hong Kong-Zhuhai-Macao Bridge is a bridge and tunnel project connecting China, Hong Kong, Guangdong, Zhuhai and Macau, with a total length of 55 kilometers, which is the longest sea-crossing bridge in the world. The construction scale of the bridge is huge and the construction is extremely difficult. However, upon completion, it will greatly promote the traffic links among Hongkong, Zhuhai and Macau, which is of great significance for promoting the regional economy and China's economic development.
