World's longest sea bridge

The world's longest sea bridge is scheduled to be opened in October 2018. The 22.9 km bridge is a part of the 55 km long Hong Kong - Zhuhai - Macau Bridge project, which also consists of an undersea tunnel of length 6.7 km and a viaduct of 9.4 km.

The project connects mainland China and Macau with the city state of Hong Kong across the Pearl River Estuary. The project also involved construction of two islands where the undersea tunnel comes out. One of these islands houses the Hong Kong customs. The Hong Kong end of the project connects to the international airport as well.

The construction of this project began in December 2009 on the Chinese side, while from the Hong Kong end, it began 2 years later in 2011. The undersea tunnel was completed by July 2016, while the entire link was formally declared compete in July 2017. It is expected to undergo a 3-day trial before being opened to the public.

Despite connecting two right-hand drive countries, the bridge will follow the left-hand drive convention and a switch over will occur at the respective custom clearance areas. The new road link is expected to cut down an hour long ferry trip to half by bus.
