They lay on 2 rivers which confluence to one. That's what Kuala Lumpur means I believe.
The contractors were UK And Australian. They were each given a tower to build, sort of competition. The Aussie won. Then a German co traitor awoukd check the builds before signing off.
They nominated a German company obersee the build
The bridge was added to keep them stable as they say on two riverbeds.

I’m always somewhat surprised that they built the bridge with visible supports that so obviously clash with the style of the building. It’s like they ran out of money and said “ah, fuck it.”
