Worried my post is too small for my heavy gate. Need advice!

Hi,
I'm still plugging away at this run I'm building. I built the door and decided to make it solid using scrap 2 x 4 's and 3/4" planks from left over materials. The door looks great, but it's very, very heavy!

I just purchased 18" heavy duty strap hinges and 3/4" pins to put through the posts, which are 4 x 4 (actually measures 3.5 x 3.5). The gate itself is 6 feet tall and 3 feet wide.

I'm now worrying that the post isn't beefy enough for such a heavy gate. I have no room to put a post in next to it since it's in concrete.

Do you think it'll be okay or should I scrap my scrap door and build another? I CAN cut some out of the top and add a piece of Lexan I have, that would take some weight off, but not much.

Thanks!

since it is in concrete you 4x4 post will be strong enough

Thanks for your reply.

Even in concrete with a heavy side load in any given rainy season a post will sag to some extent. One thing is with the gate being only 3 feet wide instead of a greater distance you won't have as much pressure as you may have bhad. How deep is the post? 2 feet in concrete if the soil was somewhat firm you probably will be fine with only a 3 foot gate.

Two main thing matter, how heavy is the gate and how deep is the post.
