The pier is glued together with four toothpicks. First, stick two toothpicks together, then stick two pairs that have been glued together, and finally cut off the sharp parts of the toothpicks. Total * * * need four piers, glued in turn, and finally cut at the same time, pay attention to the same length.

Choose the right amount of toothpicks according to your needs and put them neatly. (Pay attention to choose toothpicks with uniform thickness and no bending. If the toothpick is thick at one end and thin at the other, please arrange it at intervals in the opposite direction. Glue it roughly first, and then use two toothpicks as beams to strengthen the bridge deck below.

Finally, cut off the sharp part of the toothpick. Be sure to cut it neatly. First, cut the gaps as shown in the figure at the four corners of the bridge deck (in order to better fix the pier and the bridge deck together). The gap is square, and the side length is twice the diameter of the toothpick. Then the pier and the bridge deck are fixed together.

Finally, four toothpicks with the length greater than 1/2 are used to obliquely fix the pier and the bridge deck to form a more stable triangle. The columns on both sides of the bridge deck are added with guardrails. Add approach bridges on both sides of the bridge deck and fix them. Finally, it's done.
