The directions for assembling the bridges are good. However, the wood is not very sturdy, and the top and bottom rail broke while trying to assemble the bridge. Either the holes are not large enough, or the sticks are too wide, so you absolutely need a hammer to put it together. So while hammering, very gently, the wood breaks.
My daughter needs them for a science project, so I have to buy more kits for her, I just wish they were a little sturdier, so she can have a better ground of comparison.
