This is the bridge my son and I built this summer. It’s got twin pressure-treated 6x6 beams as the undercarriage, set in stone and concrete pylons of ~200 pounds each. We ripped and sawed the planks ourselves, also out of pressure treated lumber. Everything is attached with decking screws rather than nails for strength. It’s all sealed in Australian timber oil which was applied to each individual piece and cured before assembly; after we put it together I reapplied oil to all the screw holes to make sure no untreated wood was exposed to the weather.

Then just this week we built a French drain. I had to tear apart my fire pit and rebuild part of it afterwards, but it’s back in service. The drain worked very well during this week’s brush with the tropical storm.
