Well the last original structure on Natural Highly finally bit the dust when one of the stringers broke in half, so it was time for a new ladder bridge, as follows:
Here is a photo of the original structure, before we put in the rock roller coaster:
A slightly modified ladder bridge after the original ladder was shortened and the rock roller went in on the right hand side, providing a nice tyranny for the end of the ladder:
After demo the first post goes in (a good 2 [HTML_REMOVED]#8211;3 feet into the ground):
All posts, stringers and cross braces are debarked before use to promote longevity:
A second post goes in and they are trimmed to the right height:
Cross brace goes on top and the stringers are sized up (Note trail builders friend in the foreground):
A second support is put in mid way along the stringer span and the stringers are sized up one last time (measure twice, cut once) and checked for level. (Think we built it burley enough?);
Cross braces and stringers are notched to maximize strength and stability for nailing (12 inch galvanized in this case) and rungs are added. The rungs were salvaged from the original structure and others as we want to support the DNV[HTML_REMOVED]#8217;s BMP[HTML_REMOVED]#8217;s and pursuit of maximum trail sustainability :rolleyes:
Once the rungs have been nailed down (5 inch galvanized) the new ladder bridge looks like this:
One from the top of the A frame and yeah; it's a long way down!
Hopefully this one will last a little longer and provide many more years of fun.
Njoy.
Please let me demonstrate the ride around; really it's no trouble.
