The Golden Gate Bridge is constantly being painted. The conditions are harsher, I suppose. https://www.kron4.com/news/bay-area/is-the-golden-gate-bridge-always-

  Seeing the signs near the Golden Gate Bridge about how it's painted (EDIT: like a decade ago) made me think that it'd be a good idea to use drones to paint it. I explored that idea a bit deeper but it never went anywhere. There are/were some attempts at painting drones. I still think it'd be cool and could be made to work ;)

    I suppose the risk of pollution would be too high, but it'd make for a cool demo. Once on a bike ride, I met a guy who worked painting the GGB. He said he was about 50, but look 65, so it seemed plausible. He wasn't wearing a helmet even on descents, which I asked him about, and his answer was that he spends all day in a harness with hard helmet, so the last thing he wanted was more helmet time in the weekend.

  I thought this was a fact of all famous and suitably large bridges like the Sydney harbour and Forth bridges. Because painting doesn’t effect the running of the bridge much they just hire enough painters that gets the bridge painted in time and then start again. Apparently the Forth bridge now uses a new paint that means it doesn’t need to be painted for 20 years though
