50 km long bridges linking Hong Kong - Zhuhai - Macao

Photo taken on Sep 6 shows construction of all piers holding up the Hong Kong - Zhuhai - Macao Bridge have been completed, which means the construction work has entered the final stage. It is scheduled to be finished in late 2016.

The Bridge consists of a series of bridges and tunnels that will connect Hong Kong, Macau and Zhuhai, three major cities on the Pearl River Delta in China.

The proposed 50 km link is expected to cost US$10.6 billion. The longest bridge section will be 29.6 km (18.4 mile) long and will include three cable-stayed spans between 280 and 460 m (920 and 1,510 ft). Construction formally began on 15 December 2009.

Zhuhai / Macao - seabed tunnel exit/entr - manmade Island - manmade island - seabed tunnel entr/exit - HK


The 180 m long tunnel elements are cast in eight individual segments each 22.50 m long – monolithic, without ties and in compliance with strict dimensional tolerances.

Realization of the three-cell cross-section is achieved using the incremental launching method by means of three sets of tunnel formwork as horizontal moving device.

The internal formwork moves hydraulically over the launching beam into the reinforcement cages.

A total of 33 tunnel elements will be produced using two production lines: each 180 m long, 38 m wide, 11.40 m high and weighing 72,000 t.

The finished tunnel tubes with lengths of 180 m are moved from the field factory into a dry dock, sealed with bulkheads and lowered gradually to reach sea level. Pontoons stabilize the tunnel sections during towing operations to the lowering point in the South China Sea.

Concreting of the First Precast Pier Shaft and Pile Cap of HZMB

On 16 March 2013, two elements of 180 meters in length were precast and launched to the designated spot in the shallow dock. The size of both the elements has set a new world record, and the precasting technique is also the first of its kind in China.

On 31 January 2013, Bridge Pier 31# of Contract CB03 became the first precast pier shaft and pile cap made in the HZMB Main Bridge Project. Concreting started in the Dongguan Precasting Yard, and was completed on the morning of 21 February after three pours.

Engines and fuel injection system are not ready?!?

A matter of a couple of weeks if not days。

Just two weeks ago, I've been there by ship and I saw workers and engineering ships are busy working. I can even see this bridge at Dong Ao Island（东澳岛） of Zhuhai far away from the bridge. Just an amazing bridge!

I'd like to drive a car on the bridge when it is compeleted some day. You have to admit that it is a engineering miracle when you see it.

Engineering marvel ! Going on my bucket list.

I remember watching a Chinese documentary on this long time back when it was still in the early conceptual/design stage.

Great to see the physical manifestation taking shape.

When I am in HK later, I will take the jetfoil to Macau and get a window seat....surely there must be good views of the construction.

Shanghai Yangtze River Tunnel and Bridge

It is a bridge-tunnel complex across the south fork of the Yangtze River near the river mouth in Shanghai. The tunnel connects the Pudong District of Shanghai on the south bank of the river with Changxing Island, while the bridge connects Changxing Island with Chongming Island. In combination with the Chongqi Bridge (opened in December 2011), which connects Chongming Island to the north bank of the Yangtze, the bridge-tunnel complex forms the final crossing of the Yangtze before it empties into the East China Sea. Built from 2005 to 2009 at a cost of 12.6 billion yuan (US$1.84 billion), and opened on 31 October 2009. Their combined length is 25.5 km, forming part of the G40 Shanghai–Xi'an Expressway.

Cross-River Tunnel Section

It is 8.9 kilometres (5.5 mi) in length, and has two stacked levels. The upper level is for a motorway, and has three lanes in each direction. The lower level is reserved for a future Shanghai Metro line. The tunnelling was completed using four world's biggest tunnel boring machines, the largest of which was 15.43 metres in diameter, 135 metres long, and weighed 2,300 tonnes.

Cross-River Bridge Section

It consists of two long viaducts with a higher cable-stayed section in the middle to allow the passage of ships. The total length is 16.63 kilometres, of which 6.66 kilometres (4.14 mi) is road and 9.97 kilometres bridge. The overall shape of the bridge is not linear but slightly sigmoid ("S" shaped). The central cable-stayed span is about 730 metres, the longest span of any bridge in Shanghai, and the 10-th longest cable-stayed span in the world. The bridge has three road lanes in each direction, Room on both flanks of the bridge is reserved for a future Shanghai Metro line, so total deck width is 35.3 m.

Got to say, China has some beautiful bridges!
