Engineering The Future: HK-Zhuhai-Macau Bridge

China.org: Construction of HK-Zhuhai-Macao bridge making progress
Starting from the Lantau Island in Hong Kong, the Y-shaped bridge will have a total length of about 55 km, including a 6.7 km underwater tunnel and a 23-km bridge over the sea, making it the longest cross-sea bridge in the world.

The bridge will serve as an important channel linking Hong Kong, Macao, Zhuhai and the western part of the Pearl River Delta, one of the most economically-developed areas in the Chinese mainland.

The government should publicise the monitoring results of construction work on the bridge linking Hong Kong with Zhuhai and Macau every month so as to ease public concern about the repeated drifting of an artificial island, a critic of the massive infrastructure project says.

Concerns have been raised about whether the drifting will continue intermittently or is just sporadic in nature. “If the movement proves to be periodical, it means that the tunnel linking the island [to Tuen Mun] can never be completed,” warned Professional Commons convenor Albert Lai Kwong-tak.

“The government should address public concerns by releasing its monitoring data every month to update the project’s progress.”

The Hong Kong side of the bridge project was held up for a year by a judicial review of the project. It was hoped that this period could be recovered by speeding up construction. But in a classic demonstration of the old adage ‘more haste less speed,’ this has contributed to further delays. These have occurred as a result of the non-dredge reclamation technique adopted for this project – the first, (and probably the last) time the technique has been used in Hong Kong.

Parts of the island, particularly the sea-wall, have been moving. Engineers say this is because in attempting to speed up the settlement of the reclamation, too much weight has been applied too quickly. This has changed the nature of the marine mud and in effect turned it into ‘toothpaste’ resulting in unanticipated movement. (See links at the bottom of this story for more on this).
