Cantilever bridge

Building the shortest bridge is easy, but to build the medium length one visitors need to balance the bridge they are building out into the river by extending their structure out on the shore side too, and then stacking extra blocks to balance those that stick out furthest. Once the medium sized bridge is built, spanning the widest section of river is a matter of scaling up the same principles, which encourages builders to really think about what they are doing.
