I'm NOT so sure the wall will be carefully maintained everywhere. Political & economic winds change--sometimes at a frightful speed.

Then there's two countries--currently--involved. One of which has more investment in destroying a wall than in helping maintain it.

I'd vote for the minimum maintenance needed sort of wall.

Yeah we should probably just give it will never work. /Sarc

Or perhaps you have some actual information or sources that prove that a concrete wall will last longer and require less maintenance other than your opinion...

Many of the great landmark bridges are constructed of steel. Still, it’s important to note that steel bridges aren’t just attractive, they’re generally stronger, safer, faster to build, require less maintenance, and are more flexible, which makes them perfect for earthquake-prone and high-wind sites. Steel is also used to protect elements on bridges, including utility infrastructure.

In addition to all this, environmentalists are more likely to support the construction of steel bridges compared to other types because they’re generally more sustainable and earth-friendly

I think you’re in a “glass half empty” mood tonight.

I’m so hopeful I’d do a dance if my r foot wanted me to.
