Actually Ting Kau Bridge is my favourite in HK, but let's see what happens to Stonecutters.

HK's tropical typhoons pack quite a bit of wind, and having that support tower in the middle mitigates this effect on the bridge.

Looking east, to city (Tsing Yi island)


Looking west, to airport (with Kap Shui Mun bridge between Ma Wan island & Lantau island; Kap Shui Mun is the name of the channel)


Looking northeast (with Ting Kau bridge between Tsing Yi island & Ting Kau)

Inside Tsing Ma Bridge


Tsing Ma
total length 2160m; longest span 1377m; height 206m; clearance below 62m

Ting Kau
total length 1875 m; longest span 448m, 475m; height 194, 167, 162m ; clearance below 60m

Kap Shui Mun
total length 750m; longest span 430m; height 150m; clearance below 47m

WOOOW!!! I only have two things to say:
1) Would this network of bridges and tunnels connecting Kowloon to Airport be the costliest transportation network built b/c of the construction of the airport? And,
2) AFAIK, the 2 carriageways to the sides of the AEL (Airport Express) are for use during emergencies or typhoons.

The bridges themselves are nothing that special, plenty examples of things similar to that around the world, but the proximity of them to each other makes it an amazing view, if you get the right shot!

Awesome !

1-km isn't that long, there are plenty of simply supported bridges with that span over water out there.

The decision of using a cable-suspened bridge over supporting beam/column was because there is a need of 50m+ height clearence and wide open water for container ship travel underneath. Supporting from below would not allow the wide gaps between supporting structures and could be very dangerous if there was a container ship collide into the bridge. The bridge could actually fall down with the massive momentum. This concept applies to Tsing Ma and Kap Shui Moon Bridges also.

Second, a three-towers cable-stayed bridge was used because Tsing Ma Bridge was right there, and it would give a more diverse bridge type in the area rather than two identical bridges. Simply, looks better.

I cannot think of any simply supported bridge with a 1-km long span in between two columns though...?

I was thinking series of simply supported bridge (multi-columns over the distance).

[gladisimo]

I dont think it is possible (or else very very costly) to build a 'simply supported bridge' with a single span of over 1km, as the stress would not be transferred else where. (I'm guessing by simple u mean either girders, box girders or beam bridges)

And building an artificial "island" is hardly new. Though it isn't really an island the SF Bay Bridge built an artificial concrete anchorage for two suspension bridges, and mapped the crossing through the natural treasure island in order to reduce costs.

Guys, how about that bridge that they are building over the channel at that containerterminal near Kowloon. Saw sometime just yet on discovery so I was wondering if there is any more info on it or better yet: pictures??
Thanks.

There are to be more bridges with diverse outlook in HK:




Deep Bay Link (in use in 2007)
A 3.5km carriageway over the waters between Hk and the nearby Chinese city, Shenzhen. It is intended to be a high-capacity boundary crossing freeway between the 2 mega cities.




The far side of the 2nd pic is Shenzhen

****************************************************************
Stonecutters Bridge
(under construction, date of completion:2009)
With a central span of 1,018 metres, over one of the busiest container port in the world, the bridge will be the longest span cable-stayed bridges in the world.

HongKong-Zuhai-Macau Bridge
(Under active planning)
A 35 km bridge-cum-tunnel link over the Pearl River Estuary, connecting HK and 2 cities (Zuhai and Macauu, where Macau is now the biggest gamble city in the world, surpassing Las Vagas in terms of revenue) on the western bank of the delta.

****************************************************************
Tsing Lung Bridge
(plan withdrawn and restudied)
The Tsing Lung Bridge will be a suspension bridge with a main span of 1418 metres between the towers, which is 41 metres longer than the Tsing Ma Bridge. It will become the fourth longest suspension bridge in the world upon completion. However, due to slow growth in traffic and the opposition from the residents, the plan was pulled back and might be replaced by alternate road link. Implementation time is still indefinite.

This figure shows the position of the Tsing Lung bridge relative to the existing Tsing Ma Bridge, Ting Kau Bridge and Kap Shui Mun bridge




If the Tsing Lung Bridge is completed, it would be an amazing scene of 4 such mego bridges in incredible close proximity. The Stonecutters Bridge is just on the bottom right of the map, on the opposite corner of the Tsing Yi Island.

Hong Kong region does not need these many bridges. The airports, ferries, existing roads, and mass transit are capable of handling traffic, perhaps more emphasis on using mass transit. I believe they're over planning growth and future usage < capacity.

[EricIsHim]

^ If the central core can't handle the traffic, it doesn't matter how the outside network expand but it still wouldn't help the city traffic.

From capacity point of view, Tsing Lung isn't necessary. It only connects Tuen Mun and Lantau not a direct link to the boarder. Tsing Ma, Ting Kau and Route 3 serve that function better. The link is nowhere near its capacity. The problem is commercial traffic doesn't want to pay the tunnel fee and using Tuen Mun instead. But I guess it is still good to have a second link connecting Lantau and the mainland just in case there is something happen on Tsing Ma.
