Arch bridge

This is the third bridge we built. We put the "road" above the arch.

A picture taken by Gaby when I was putting together one side of the arch. I had to make a straight sequence of k'nex, then contort it into an arch with spoke-like pieces that connected another straight line sequence of k'nex.

The arch bridge was a little bit harder to build than the other bridges because to form the arch shape, we had to bend the k'nex in an unnatural way.
