Some people aren’t satisfied with great function and appearance. They have to add their own vision of “beauty” to things. Usually detrimental to the function and durability of the structure. Just can’t leave well enough alone, constantly reinventing the wheel.
Give me simple elegance that endures and I’m happy. No need for overly expensive “art” on my roads.
Incidentally, the over 2 mile long suspension bridge photo I posted just above cost just over 1 billion euro, and was completed on time and budget. The state approved design for the replacement Bay bridge destroyed in the Northridge quake cost more than $5 billion (3 billion over budget), and was delayed over a year.
Some things standardized/state sanctioned design works for. Others, not so much...
