originally made from stone and over time people discovered that iron and wood have great strength when used under tension and compression.

No tourist strayed to this impassable height‚ the bridge was not yet traced on any map. So I lay and waited; I could only wait. Without falling‚ no bridge‚ once spanned‚ can cease to be a bridge. It was toward evening
