NO.1 the bridge between zhuhai, Hong Kong and Macao is 49.968KM
     The hong kong-zhuhai-macao bridge is a huge bridge connecting Hong Kong, zhuhai and Macao. It has important strategic significance in promoting the further economic development of Hong Kong, Macao and the west bank of the pearl river delta region. The hong kong-zhuhai-macao bridge is 49.968 km in length, and the main project "haizhong bridge and tunnel" is 35.578 km in length with a design speed of 100 km/h.

The bridge will cost more than 100 billion yuan and take about 8 years to complete. With the successful lifting of the last piece of steel box girder weighing 1,950 tons on March 30, 2016, the lifting of the box girder of the non-navigable hole bridge of the main project of the hong kong-zhuhai-macao bridge was completed on March 30.
