Hong Kong-Zhuhai-Macau Bridge..
The in-construction
Hong Kong-Zhuhai-Macau Bridge is a series
of bridges and tunnels that will connect the west side
of Hong
Kong to Macau and the mainland Chinese city of Zhuhai, which are situated on the west side of
the Pearl
River Delta.
The proposed 50 kilometres
(31.1 mi) link is expected to cost US $10.7 billion.

With its length, it would
become one of the landmarks within the area. Though overall length
exceeds the Second Lake Pontchartrain Causeway
in the United
States, which is
38.4 kilometres (23.9 mi) long according to the
Guinness Book of World
Records,
the longest bridge section (between the artificial islands
containing the Macau exit of the tunnel and the Macau border
facilities), which will include three cable-stayed spans with spans
between 280 and 460 m, will be 22.8 kilometres (14.2 mi)
long. Construction formally began on 15 December 2009. It
is due to be completed in 2016.
