ou might wonder why foil, and if that would attract more heat — it’s actually part of a cooling system designed to reflect sunlight and keep the bridge at a moderate temperature so its materials don’t expand and crack.

To reflect the radiation, it would need a mirror surface. That aluminum is Gray, that is 1/2 black. Ever pick up a shiny chrome wrench and burn your hand?

Maybe if they set up a chimney around the pillars for air flow to pass upward???

Now, painting the RR rails white is the better soln. White will reflect most of the radiation, way better than that 1/2 black aluminum foil.

I just looked up the pictures. Not impressed.

Way better to have painted it white.

But, you know, that is supremacy.
