If you're also excluding sea travel, if you're in North America, you can travel from Alaska, Yukon, Northwest Territories, or mainland Nunavut, to at least the Panama Canal. If you can drive across it, you can travel to either Ushuaia, Argentina or Punta Arenas, Chile entirely by car.
My memory might be failing me, but I don't think there is a bridge linking Tierra del Fuego and mainland Chile/Argentina, so Punta Arenas yes, Ushuaia no.
Also I think there is no road connection between Panama and Colombia. I assume this to be the case since the Pan American Highway has a known gap in this region, plus I couldn't find any roads looking on Google Maps (which could be incomplete there).
