| Jan 11, 2017 at 20:56 | comment | added | RBarryYoung | There are a number of bridge-building techniques used by military engineer that build form a single side (Bailey's bridge en.wikipedia.org/wiki/Bailey_bridge, etc.), but without advanced technology, I am not sure if any of them can span a 1/4 mile gap reliably. | |

| Jan 11, 2017 at 11:45 | comment | added | Graham | To echo Matt Bowyer, the technology and resources available are going to make a huge difference. Do they have steel cables, or only natural fibre? Do they have artificial fibre materials for balloons or other constructions, or only natural fibre? Do they know Newton's Laws? Or aerodynamics? Do they have engines of some kind (steam or internal combustion), horses, or purely their own muscle power? Do they have computers, or pocket calculators, or log table books, or abacuses? The solution for a well-equipped modern military engineering division would be very different to that for Moses! | |

| Jan 10, 2017 at 17:53 | comment | added | Jason K | May be easier to start at the bottom and build UP to the base of the floating island. Dump enough earth over the side of the ravine and you can dam it up. This is the LEAST amount of technology (but probably the GREATEST amount of effort!). | |
| Jan 10, 2017 at 17:44 | comment | added | jamesqf | @JDługosz: Nope, Caesar's bridges were built with pilings, so his workers only needed to do a short span (maybe one tree trunk length) at a time, and could work from boats in the water. The engineering's entirely different, and much simpler, than trying to build a half-mile unsupported span. I'm not sure even modern materials could manage that, but as above, refer to Engineering :-) | |

| Jan 10, 2017 at 15:12 | comment | added | Matt Bowyer | I think that we need to know what level of technology and materials are available. Can you build hang-gliders, fly crews across, fire ropes to them and make a zipwire? Or can you just build an enormous cantilever or cable-stay bridge? Cable-stay is generally held to be practical for 1km+ spans (from both ends) which means that 500-600m (well over quarter of a mile) is perfectly plausible for a single-ended bridge with today's technology. | |

| Jan 10, 2017 at 10:06 | comment | added | Grimm The Opiner | I think you might need a combination of improbably powerful siege weaponry, extremely lucky shot with a big harpoon, insane amounts of insanely thick rope (particularly insane amounts for displaced refugees), extremely brave folks to climb up or shimmy along it, and maybe access to the coast and ships to sail to beneath the island. Hang gliders are technologically simple, but require a fair amount of scientific understanding to even conceive - and they require practice to use! So, just use giant tame birds. : ) | |

Forgot to add how far the island is!
