I was privileged to witness it's annual renewal in 2006and to walk across it on the day of its completion. It was much steadier than some other swinging bridges I have visited. Of course, the ropes are made of grass and I'm sure I would feel less secure as the bridge aged.Bridge Inknoreply@blogger.comtag:blogger.com,1999:blog-6470543006314152962.post-44981005852316935302012-10-05T11:06:37.069+01:002012-10-05T11:06:37.069+01:00David, thanks for the kind comments.

The Peruvian rope bridge is on the face of it safer than the Invermark one - it is largely suspended from its "handrails", so the centre of mass for anyone crossing it is below the point of suspension. At Invermark, it is suspended only below the deck (the "handrail" wires are not taut), and so the centre of mass is above the point of suspension. This make it feel quite unstable when you cross it, although as it begins to move laterally, the other wires do pick up some force and resist movement.The Happy Pontisthttps://www.blogger.com/profile/15252272118786667592noreply@blogger.comtag:blogger.com,1999:blog-6470543006314152962.post-63325835323108980912012-10-05T09:09:50.391+01:002012-10-05T09:09:50.391+01:00HP,

Your latest bridge reminds me of this “keshwa chaca” Inca rope bridge: <br />http://www.rutahsa.com/k-chaca.html <br /><br />You must have travelled so many kilometres through wild country, including on foot to visit all those bridge sites! A Scottish bridge across the Forth that piques my interest from the historical aspect is the Old Stirling Bridge:<br />http://www.thesonsofscotland.co.uk/Photos/History/Stirling-Bridge-Plaque.jpg <br />Very little is known of the original bridge; it was probably a timber structure located near the existing New Old Stirling Bridge. <br />http://canmore.rcahms.gov.uk/en/site/46195/details/stirling+causewayhead+bridegehaugh+road+old+bridge/ <br />Remnants of stone foundations of the “Old Old Stirling Bridge” were located in the 1990s:<br />http://canmore.rcahms.gov.uk/en/site/46113/details/stirling+bridge/ <br />Thanks for sharing your bridge experiences with us, DavidDavidhttp://sites.google.com/site/constructivedevelopments/noreply@blogger.com
