Medium 3

This is an 80 m car bridge, two cars cross from either direction and a ship passes under the bridge. I built this bridge as cheaply as I could and consequently it is a little wobbly. Despite this, it is still slightly more expensive than the world record, but I don't think I can trim this particular design down any more. It is supposed to be a drawbridge, but I just made a "high bridge" to save money.
