@wolfgang59 saidIt was longer, wow, guess you win.
@XYYZ

Earlier than the Chunnel and longer.

@ponderable saidNot just my pyramids ... ALL OF THEM
@XYYZ
Thy pyramids all over the world (and a few thousand years old)
@Ponderable- Thy pyramids all over the world (and a few thousand years old)
Update:
1st--Pyramids (massive, designed & built in the bronze age)
2nd--The Chunnel & Seikan Tunnel. (tie)
@wolfgang59 said8 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.
@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.
@shallow-blue saidas you can the "chinese wall" another marvel 😉
@XYYZ
The Dutch polders. One engineering work you actually can see from space.
@ponderable saidThe 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.
