Stability

Various General Tips

You should always use a basic triangle pattern for building your bridges.

While the bridges basic building unit should be triangles, the overall look of the bridges should be oval, to better distribute the weight.

There are three secret achievements in Bridge Constructor: Stubborn (25 failed simulations in a row for the same bridge), Smart Alec (if you don't build the 1st level to specification), and Safe Flight (ran a simulation even though you didn't place a single element), all of which are worth 10 points.
