From Limex Games:
"The Cargo Bridge is back! Build a bridge and test your construction skills. Now, there are more levels, more bridge connections, more cargo and more fun! Design a bridge on a blueprint and test it when you are done! Your workers will use the construction to get cargo located at the other side of the valley, and bring it back. Your goal is to collect all items in each level."
You can play the game in the tiny version here, or full screen online, download it, and also find it in the iTunes store (iPad and iPhone).
