It consists of a series of three cable-stayed bridges and one undersea tunnel, as well as 3 artificial islands. It supports 6 lanes of traffic.
The multibillion-dollar bridge will put the three cities within an hour’s commute of each other.
It cost over USD2 billion.
Construction on the Chinese side began on 15 December 2009. Construction of the Hong Kong section of the project began in December 2011 after a delay caused by a legal challenge.
The construction of the main 29.6-kilometer (18.4 mi) structure, both the 22.9-kilometer (14.2 mi) bridge section and the 6.7-kilometer (4.2 mi) undersea tunnel, was formally declared complete on 7 July 2017.
US infrastructure costs twice as much as the UK. Spain gets 10 to 20 times as much infrastructure for its money as America does, and it is of much higher quality to boot.
The major US high cost factors are
* Expensive labor (US uses 25 workers while Spain can use 9 for a common type of task)
* Out-of-control private contractors
* crappy procurement
Every American infrastructure project has a scramble on the part of all parties to skim as much for themselves as possible. This leads to a self-defeating cycle. Voters do not want to pay for new and overprice projects. Elites fund new projects in bad ways which only leads to more cost overruns.
The Eastern span of the San Francisco Oakland Bay bridge was replaced after Earthquake damage. It cost $6.5 billion to replace.
The eastern span replacement was the most expensive public works project in California history. It cost 25 times more than the original estimate of $250 million. Originally scheduled to open in 2007, several problems delayed the opening until September 2, 2013. It is 2.2 miles long.
The Ohio River Bridges Project was a Louisville metropolitan area transportation project involving the reconstruction of the Kennedy Interchange (locally known as “Spaghetti Junction”), the completion of two new Ohio River bridges and the reconstruction of ramps on Interstate 65 between Muhammad Ali Boulevard and downtown. It is estimated to cost $4.1 billion.
The Abraham Lincoln Bridge (2100 feet long), opened December 2015, is located downtown and slightly upstream from the John F. Kennedy Memorial Bridge which was completed in 1963, for relief of I-65 traffic. The other, the Lewis and Clark Bridge (2500 feet long), opened December 2016, connects Indiana SR 265 and the Kentucky segment of I-265 (via KY-841) between Louisville’s East end and Utica, Indiana.
