@wolfgang59said @XYYZ The Chrysler building.
Tallest building in world for just a year but far prettier than the Empire States.
St Paul's Cathedral (London)
Tallest building in UK for 250 years.
Burj Khalifa is almost 8 times taller.
8 times taller? Engineering advances in design, materials and trained/skilled construction labor. How about the longest bridge expanse; 3 come to mind without Google- In Louisiana, over the swamp lands or the Florida Keys bridge (if you add all the expanses as one) and in Japan. I don't know the names because I didn't look it up, more fun this way.
@ponderablesaid as you can the "chinese wall" another marvel 😉
The Hong Kong–Zhuhai–Macau Bridge, officially the Hong Kong–Zhuhai–Macao Bridge, is a 55-kilometre bridge–tunnel system consisting of a series of three cable-stayed bridges, an undersea tunnel, and four artificial islands. It is both the longest sea crossing and the longest fixed link on earth.
It's like an oversized version of the Øresund or Öresund Bridge, which is a combined railway and motorway bridge that becomes an undersea tunnel across the Øresund strait between Sweden and Denmark. It has a total length of 7.8 km.
