==How to do it==
<ol><li>Single Tile width (wasting dirt!)</li>
Drop dirt on each corner off the deep end of the land bridge to bring each corner up to the same height.
<li>Single Tile Width (Not so much wasted dirt!)</li>
Drop dirt on the left side of the tile off the end, when its above water, flatten the tile, repeat until both front corners of the tile are above water.
<li>Single Tile Width (Not wasted dirt! More time consuming.)</li>
Plan...
<ul>
<li>1. Drop 16 dirt on tile 1 corner a corner.</li><li>2. Drop 16 dirt on tile 1 corner c corner.</li>
<li>3. Flatten tile 1.</li>
<li>4. Flatten tile 2.</li>
<li>5. Start flattening tile 3 until the tile's 2 corners e and f will be in water level or tile 2 slope will be 20 dirt.</li>
<li>6 . Flatten tile 1.</li>
</ul>
Start everything from step 1 until all 3 tiles will be are flat.
Process explanation.
So where is the secret? Very simple, first you rise raise tile 1, then with flattening help you move dirt to tile 2 and then to tile 3.
This way of land bridge building is good when you don't have enough place to build a 2 tiles wide bridge or you don't want to spent spend the rest of your wurm life by diging digging dirt for a 2 tiles wide bridge.
<li>Double width (No wasted dirt!)</li>
