Fixing driveway/road dip

I use to have 6, 10 foot 2X10's that I used to get the trailer in and out of the driveway. Built a cart to move them around but would have to lay them out with support under to get in and out. Put 2 down and one on top. My son spray painted the outline so we knew where to put them. They got beat up pretty good over the 2 years and what a pain they were. Pull out some, set them out, get in the street, park, put boards away, come home, park, set up boards etc etc to put away and usually 90 degrees out on a Sunday afternoon. After 2 years we traded in the trailer for something higher.

Good luck, the key is to get as strong as you can but keep them as light as you can.
