Own a car in Hong Kong and want to drive across it to Macau? You need to get vehicle registration plates (some "electronic" or temporary) in 3 jurisdictions. You also need insurance for 3 jursidictions. Also, you can only drive to a parking lot outside of Macau and then transfer to public transit to enter the city. And you need to register for a parking space 12 hours before your trip. Watch this hilarious HK government video on the process: https://www.youtube.com/watch?v=NO3bNlB9j9o
But you don't own a car! Like most Hong Kongers, you take public transit. Surely this bridge will make it faster than the 1 hour ferry ride that leaves from 2 ferry piers in the middle of the city every 15 minutes or so all day and night. Unfortunately this isn't the case. The buses across the bridge from Hong Kong leave from the airport and take 40 minutes. You'll have to take another bus from the airport to the city at the cost of another 45 to 60 minutes.
This is a political project to show that Hong Kong and Macau are being integrated into China.
As political projects go, this certainly isn't the worst of them. It's better than the other things governments do to bolster domestic support like wars or locking up people you don't like. At least we'll all get to have a fun day trying out the bridge and something for tourists to take pictures of as they land in Hong Kong and Macau.
Perhaps in the future policies will change and it will become easy to us the bridge as a normal bridge.
