Bridge construction?
Answer:
Same as today. You get a light rope, called a messenger line, across any way you can. This could be throwing a weight, suspending from a kite, or dangle into the chasm then pull the loose end up the other side. You use the messenger to pull heavier ropes across. If the gap is small enough, you can pull the main ropes across directly, without messenger lines.Once you have the big ropes, called suspension cables in modern bridges, you start at one end and build the road base across. If you've invented the wheel, it's easier, because once you have a single cable of reasonable strength across the gap you can suspend stuff from a pulley hanging on the cable and pull a lot of it across easily. Reference is to an Andean population that builds a new bridge every year, starting with grass along with rawhide and some sticks.
