I have just built a 6 foot fence all the way around my property. To finish it offI need to build a driveway gate. The gate will be 15 feet wide and have two swing gate sections. I have used 4x4x8 foot posts buried approximately 26" and cemented.
I was considering bolting two posts together and burying them at the same depth, but I am concerned that it still may not be enough support. The gates will have wheels on the bottom also.
