This set builds some awesome bridges. I got it for my 4-year-old's Christmas gift, because he's into bridges and building things. He has already built a bridge all on his own. It might be a little tough for some younger kids (the box says 8+), but if you have a kid who likes putting things together and tinkering, this set is fantastic. I have a ton of fun doing it with my son; we're already looking at getting the "big bridge" set from K'nex as well.
