I support the project for transportation is the major factor when a country is developing. There is an example in USA, a almost completed highway network to bond all the states together when air travel is not popular. Imagine one day, if you need to finish a project about shanghai economy, you can go to  shanghai library in the morning & back at night. don't be short sight. HK can afford the price & if it is not building will cost more in the future unless you want HK is a isolated place in China.
