World’s Longest Sea Crossing: Hong Kong-Zhuhai Bridge Opens

The title of this post is the same as this article on the BBC.

It certainly looks to be an impressive bridge.

But I think it shows just how far design and construction of large bridges has moved in the last couple of decades.

In A Solution To The Northern Irish Problem!, I proposed building a fixed link between Northern Ireland and Scotland.

The Chinese bridge has a length of 55 km, whereas a link between Northern Ireland and Scotland would be about 30 km.

Conclusion

I wouldn’t be surprised that the opening of the Chinese bridge will push politicians, engineers and financial institutions to look seriously, at a fixed link across the North Channel.

  1. The Chinese bridge is across a shallow delta. Apart from a shortish tunnel under a shipping lane and a couple of longer bridges the whole structure is basically two connected piers built on piles. The population served is nearing 50M. Both the Hong Kong and Chinese economy have been particularly vibrant.

    The cost was reported as £15Billion, although this seems very high compared with the comparable: –

    The channel between Northern Ireland and the Rhins of Galloway is shorter, but mostly over 100m deep, so a bridge would be impractical and a tunnel difficult. As with the Chunnel it would need to be rail.

    The direct connection from the WCML to Stranraer was lifted by Dr. Beeching and the A75 is dire, so more would need to be spent sorting them out.

    Even assuming the cost was pro-rata it would be around £8 Billion or over £10,000 (approx. half a year’s median income) for every household in Northern Ireland.

  2. There was a report in the Sunday Times, where a Professor of Engineering at Sheffield University proposed a new form of suspension bridge.

    But I only said, that everybody would look seriously.

  3. This loyal reader has been hard at work on a part of that project for three years! Very satisfying to see it open at last.

    (By the way,a few years ago I also worked on the China High Speed Rail connection in Hong Kong which opened last month – I think you also posted about that recently)

  4. Do you agree that given what we have seen in recent years, that a rail-bridge between Scotland and Northern Ireland is now possible, given the political will and some superb engineering?
