Bridge It

Can you solve the puzzles and avert disaster? Bridge It is set in colorful deserts and dense forests, and it's your task to strategically design and construct bridges--ranging from suspension bridges to drawbridges--as unsuspecting motorists, heavy freight trains, and tourist riverboats approach. If that weren't enough pressure, your bridge must also be able to withstand earthquakes. If your design is clever enough, you'll receive points to boost your overall score. However, if your solution doesn't stand up to the test, tons of mangled steel will plummet into the river below.
