A tunnel under Arcabuco

The town is Arcabuco, passed maybe fifty or sixty times on the Bucaramanga road since childhood ▸ 16:38, never slept in, known mostly through agua panela con queso stops ▸ 20:35, and yet: “ese pueblito tiene mucha esencia, mucha personalidad” ▸ 17:42.

The vision he’s carried since adolescence now has engineering. Near-term: since the highway is the town’s burden, sink it, a tunnel carrying cars and trucks under the city, leaving the surface with few or no vehicles, “una ciudad 100% libre de carros y para caminar” ▸ 20:53, the exact antidote to the emptied sidewalks he’d been mourning days earlier. Long-term: flying vehicles dissolve the road constraint entirely, and once roads stop dictating where buildings can live, you can build into the mountain itself ▸ 18:49, drones docking at towers grown into cliff faces, “todo así medio solarpunk” ▸ 19:43.

Julia supplies the civil-engineering veto in four words: “¿y el alcantarillado?” ▸ 19:14. Flying cars free you from roads, not from sewage, water, and the buried networks that actually anchor a house to civilization; the remote dream-tower still needs pipes. It’s the right objection, and it doesn’t kill the vision so much as scope it: what the tunnel version has over the flying version is that every piece of it exists today. Some cities are waiting for technology; Arcabuco is mostly waiting for someone to take its geography personally…
