    • Yes, it has acrylic roofing arch supported on side beams and equipped with two escalators which was sort of advanced in HK those days.

    • I like the many arches and the light roof . . . the design was later repeated in the Hill Side Escalators up Mid Levels ( the longest outdoor public escalator ) by my colleagues. Yes, it was gratifying . . . . . I didn’t visit the bridge after the construction was finished; until now πŸ™‚

    • Many of the bridge designs are supposed to stand 120 years. I didn’t visit the footbridge since the 1980s, but have the chance to visit it last month.

    • 120 years is the design life in contemporary British or ISO ( International) codes of practice. That if, if the design and construction is carried out to the codes and regular maintenance is carried out throughout the bridge’s life, it will remain usable for 120 years.
      Problem with today’s bridges is that reinforced or prestressed concrete are invariably used; especially for long span ones.
      Masonry bridges can be used for centuries if they are properly designed and maintained as they won’t be subject to corrosion, cracking etc. Some of them failed because of overload, erosion by rivers, seismic events etc.
      The bridge at Genoa recently failed after maybe around 60 years of use – poor maintenance and the adoption of a design which has no redundancies – failure of a single cable can lead to the progressive failure of the whole!

    • I had forgotten the bridge at Genoa. A shame. You’r re right, the materials are what define the life span. Stone will defy centuries. Concrete, steel and cement won’t.

    • There are many bridges which collapsed; like the Florida footbridge which collapsed under construction about a year ago – that has more to do with design / construction staging faults πŸ™‚

    • Design, execution and maintenance are the key; Genoa bridge collapse is more of a maintenance issue albeit there is a weakness in the design.

    • Maintenance or lack thereof is mainly a problem of greed. “Oh, let’s space maintenance visits. It will cost less. Oh. Why paint the metal with anti-corrosion? too expensive. Regular paint will do.” 😦

    • Other bridges have collapsed due to design faults / workmanship problems / construction staging errors etc – like the footbridge near Uni of Florida last year. Bridges are fascinating . . . . . . .

    • Yeah, bridges are a positive thing, gives one the notion of making connection. . . . . . . unfortunately, I digressed later into other areas.

    • You are quite right. Had not thought about it. Connection. Two banks of a river. People on either side. Two parts of a city. Xie xie for the thought.

    • Yes, Friday 17th afternoon; maybe 17:00 hours after an examination of the lymph nodes before hand. Many thanks for sending your blessings our way πŸ™‚

    • She has to register at the hospital at noon. Operation is rescheduled to 8pm. Probably, fasting after noon; we will wait for the hospital instruction.

    • She has very strong will and quite a unique personality. One of the reasons why I don’t mention her name in the photos she has taken is that she doesn’t want it.
      Any way, thanks so much for your good wishes πŸ˜ŠπŸ˜ŠπŸ™πŸ™

    • I think it is perfectly all right for her not to want her name on a blog. Very sound. As a matter of fact, I don’t normally put the names of my family on the blog.. How did it go? By now it should be Saturday morning. Good news I hope.

    • Some bloggers here asked why I don’t give the name of my wife – this is certainly not out of disrespect.
      My wife fast from 8:00 am for maybe 16 hours before she has any food. She woke up after 2+ hours from the operation; appears OK.
      She was on monitored anesthesia with sedation. She experienced high blood pressure after the operation. I will make my way now to see her πŸ™‚

    • I try not to ask those things. Personal choices.
      By now, your wife should be in full recovery, maybe even home. I hope everything went well.

    • She’s home and not feeling any pain; however, this is only the start of the battle to avoid future recurrence the treatment of which depends on the pathological report.

    • Home is good. Take it one day at a time. And travel somewhere close as soon as th Doctor gives the okay. All the best Bro. (and if you are my bro, she is my sister.in-law. Give her my best regards) πŸ˜‰
