We wouldn't have such a hard time building and funding infrastructure if it was covered in Neon colors and cool shapes instead of just being grey concrete
Why you ask? Simple both Federal Officials and Investors are like small children, they are drawn to bright colors like moths to a flame
Also because I want us to make bridges bright fucking pink or green because it would be fun
You're not wrong in that it would get people's attention, however:
I can see so many unironic headlines like this.
[Image ID: A train with a rainbow pride livery crosses a stone bridge. In the lower corner is a caption labeled “The God damn News: Obama Put Chemicals in the Diesel turned the trains gay” next to the caption is a question mark in a diamond]
What would make a neon yellow Bridge get viewed as any more queer than any other bridge exactly?
