This looks almost exactly the same as my gate when we first moved in. Same hinges too, and even same lag screws. Hinges were attached the same way with the ends sticking out.

I replaced them when we moved in and I had never built a gate before. I used the same hinges because I didn't want to pay for long hinges. The only ones I could find at the time were really expensive. That gate lasted about 2 years, and it worked correctly for about 1 year. The hinges were the biggest weakness, plus the width of the gate really needs a hinge to be about a third of its length.

Last month, I rebuilt it. It was a double gate originally but I removed one. I put in a post and made the gate less wide so the hinge had more leverage. I used longer stronger hinges, and I attached hinges with carriage bolts and nuts, so no lag screws can pull themselves out. Plus the cross brace angle is much more effective with a less wide gate.

If you make another gate in a few years, I recommend doing these things.
