"They still haven't finished painting the Golden Gate Bridge!"
I'm told that they never actually "finish" painting the Golden Gate Bridge because it's a continuous process. It always needs new paint somewhere along its extensive structure.
And the signature orange paint is a thing of the past as well. It contained lead and other materials that are now deemed environmental hazards. They have been trying to get a new formulation for years, but they have had no success. The next time the Golden Gate gets painted it may end up going grey.
That's true .. it's the salty air - it "scrubs" the bridge of paint and they have to repaint it. IIRC it takes 3 years to go from one end to the next. Then .. they just start over again.
