Arched Garden Bridge
I have a lava-lined ditch dividing my yard with a garden and compost bin on the far side of it. The old 4x6 plank was a bit sketchy for wobbly seniors to use so replacing it was rather important. For this project I used 2 4x12 x 10' as the main beams and covered those with 2x6 x 4' planks. Here is how it went. Always looking for a deal, I picked up the 2 4x12's from the reject pile at the local lumber yard. These 2 were in that pile because they were curved - which suited my plans just fine.
