I made a crossover bridge for my local Cub Scout troop. The primary goal for the bridge was that it packs up into a small footprint for easy storage. The bridge is constructed from 3/4” pine plywood and a little bit of 1/2” plywood. The rope supports are cut from some 2×4 material.

The two bridge halves are ~36” long and 27-3/4” wide, and made by attaching 4” wide planks to the 3 bottom supports using pocket hole screws. The planks have a chamfer cut on each edge to make them look more like individual planks of wood.

The rope supports are 2×2’s cut from a 2×4. They sit in little stands made from the same 3/4” plywood.

The center support is painted black, and everything else is finished with DIY danish oil. I put assembly instructions on the bottom of the bridge using the toner transfer method.

The trick to the bridge is that each of the bridge halves has a sliding dovetail cut on the end. This dovetail slips into the center support to keep the bridge from pulling apart. Each support has a 5-10 degree angle cut on each end to account for the slight rise in the bridge when it is assembled.

When disassembled, everything stores under the 2 bridge halves. I attached small blocks to the underside to keep everything from sliding around, and cheap bungee cords hold everything down.

That’s cool, it’s a big deal when they walk over that bridge. My 20 year old Eagle Scout still remembers his cross over

I like the size! Our WEBELOS patrol built one out of 2X6 planks that had the 12 points of the Boy Scout Law either burned in, chiseled out, or inked, depending on what the boy wanted to do. We had 12 boys in that Patrol, so it worked out great. I had the bright idea for the 2X6 boards. I used to design ground support equipment and tooling for part of my job, but that bridge was way overkill. All 3 of my sons crossed over on it, then I gave it away. Man, was that thing heavy! You did better.
