Switchover Bridge To Link China And Hong Kong

The first time it's likely you'll have got excited by a bridge



This rendering of a swoopy bridge is Dutch architectural firm NL Architects' proposal for part of a road connection between Hong Kong and mainland China.

It neatly solves the problem of switching from an area where motorists drive on the right (mainland China), to one where people drive on the left (Hong Kong), and could form part of the 50km link between Hong Kong, Macau and the mainland city of Zhuhai and which is due for completion by 2016.

The bridge switches drivers from one side of the road to the other via a neat double-helix switchover which takes one carriageway over the top of the other.

Looks impressive if a tad low - wouldn't like to be swept away. I'm sure they know what they're doing.

Edited for spelling - missed out letter p in swept.

Got excited by a Bridge?!!

Try driving over the old Severn Crossing in a heavy crosswind, there's no crash barrier to speak of on the outside (although there is a service read a bit lower down) and it has always looked to me as though the chances of getting blown right off the damn thing are higher that they should be..

Still it's so far down you'd have time to pen a note or make a call to the designer

That looks like a damn fine bit of engineering they've got planned there!

It just shows how dedicated the Chinese are to investing in infrastructure....they must have seen what damage it's done to the UK by not investing in roads or public transport when we had the chance.

Awesome. Nothing wrong with getting excited by a good bridge.

Is this Bernie's next Far East circuit? Serious design and engineering challenge, I wouldn't like to be on it in a typhoon.

Have you been to hong kong? New York? Mumbai? Uk's infrastructure is one of the best in the world, only probelm is that the attitudes are sometimes even worse than the weather.

I do agree with the fine bit of engineering! Can't wait to see it completed!

Exactly and this is a good bridge. Love it. (Florida Keys remains my favourite bridge drive - just love the feeling of driving over water and hardly being able to see land)

Must confess I had forgotten about the Florida Keys - and the Millau Bridge, and the Golden Gate, and the Pont de Normandie... eek

Was going to suggest that Millau is worth getting excited about, and that doesn't only appear in a rendering...

Not sure the switchover bridge will solve _all_ of the problems with the mainland chinese having to drive on the opposite side of the road in Hong Kong though, when does the outside lane become the inside lane?

There's a nice bit of double helix motorway on the A89 between Clermont Ferrand and Brive too, but that is admittedly landlocked.

As stated in the comments section of Jalopnik regarding this story last month; normally in such situations where the driven side of the road changes, the traffic is made to switch over on land in the form of either a junction or small fly over/bridge.

This is just a design exercise.

More like the latest lunacy cooked up by a non-democratic government that has long catered to the interests of the all-powerful property and construction industries and the business tycoons who run Southern China.

For the same reason, buildings in this region seldom last more than 20 years, a block of luxury flats gets built but seven years later is still unoccupied, and massive white elephants like Zhuhai airport and the New South China Mall can get built.

With massive road congestion in the region despite only about 1 in 10 people in Hong Kong (and far lower in China) having access to a private car, air pollution of crisis proportions and the vast majority of freight handled via sea, this bridge doesn't exactly serve a pressing need of the people.

That's just boring. There's nothing wrong with a design exercise - it's how we make progress!

I've worked on a suspension bridge in Hongkong, and Chek Lap Kok Airport, plus tunelling projects there.

The bridge looks fantastic IMO. smile

During typhoons it will probably be closed/restricted access.

A lot of Brits are kept in employment because of these projects, one way or another.

Massive white elephants, unoccupied blocks of flats, huge shopping centres which are not exactly throbbing and a Metro where half the stations don't work, because the contractor pulled out due to non-payment. And some interesting roads with elevated sections stopping in thin air. And smog.
That's Dubai.

And an underwater section... wink

Definitely a cool design for a bridge.

What about the speed limit? I know the chinese speeding tickets are a bargain, but what about Hongkong side?
