Bridge building is a challenging task faced by many engineers today. Do you think you're up to the task? Create a stable bridge structure and see how it holds up to the crossing of different creatures.

You have the choice of wooden or steel girders during the construction process - experiment and see what works best. Good luck, the fate of so many little creatures is in your hands.

Mouse click from one point to another to lay a piece of the bridge.

Press ESC to unselect a piece.

You can click on an existing piece to remove it or you can click on a section anchor point and press DELETE to remove the section.

Press T to see how your bridge holds up.

Press ESC to return to the construction phase when your testing is done.
