Building the Base of the Bridge
When it comes to constructing your paper bridge, the base is of utmost importance. This is what sets the foundation for the rest of the bridge, ensuring that it is sturdy and reliable. In this section, we will guide you through the step-by-step process of building the base of your paper bridge. From creating the foundation to designing and constructing the trusses, we’ve got you covered. So, let’s get started!
As you begin, make sure you have all the necessary materials. If you need to make puffy paint with glue, check out our article on how to make puffy paint with glue to get started. Now, let’s dive in and build the base of your paper bridge.
Creating the Foundation
Creating a strong foundation is crucial for building a stable paper and glue bridge. A common mistake is to neglect this step and focus only on the upper part of the bridge. However, without a solid foundation, the bridge will be unstable and collapse easily.
To create the foundation, start by taking a sturdy cardboard base that is slightly wider than the bridge span. Then, use a ruler to mark the centerline of the base in the direction of the bridge span. Use a pencil to draw a line along the centerline, which will serve as a guide for building the truss.
Next, glue two strips of cardboard perpendicularly on the base, one at each end. These strips will serve as the support beams for the bridge truss. Use a hot glue gun to attach them firmly to the base.
After that, cut several thin strips of cardboard with a box cutter or scissors. These will serve as the vertical members of the truss. Use a ruler to mark the length of the strips and make sure they are all the same size.
Apply a small amount of hot glue to one end of each strip and attach it to the centerline on the base. Use the pencil line as a guide to keep the strips straight and evenly spaced. Then, attach the other end of each strip to the support beams using hot glue.
Repeat this process until all the vertical members are attached to the base and support beams. Once the glue is dry, reinforce the joints with additional bits of cardboard and glue. This will make the foundation sturdier and more resilient.
By following these steps, you will have created a solid foundation for your paper and glue bridge. This will ensure that the upper part of the bridge can be attached securely and withstand the weight of the load.

Truss Design
The truss design is an essential element to ensure that your paper bridge can withstand the weight and pressure put on it. The truss is the framework of support that distributes the load of the bridge evenly. There are several different truss designs to choose from, such as the Warren truss, Pratt truss, Howe truss and K-Truss.
Warren truss: This truss design is one of the most commonly used in bridge construction. It consists of equilateral triangles, which provide strength and stability to the structure. To create a Warren truss, cut strips of paper that are twice the length of the bridge span. Fold each strip into a triangle shape, then assemble the triangles together by gluing them at the corners.
Pratt truss: The Pratt truss is another popular design that uses a series of diagonal members to support the load. To create a Pratt truss, cut strips of paper to the length of the bridge span. Fold each strip in half and then in half again to create a rectangular shape. Cut out triangles along the edges of the strip, leaving a narrow band of paper in the center. Then, assemble the truss by gluing the diagonal members between two parallel chords.
Howe truss: The Howe truss is a modified version of the Pratt truss that uses vertical members instead of diagonal ones to support the load. To create a Howe truss, follow the same steps as for the Pratt truss, but add vertical members to the center of the truss design.
K-Truss: The K-Truss design uses vertical and diagonal members to provide strength and stability to the bridge. To create a K-Truss, cut strips of paper to the length of the bridge span. Fold the strips in half to create a rectangular shape, then cut two diagonal lines at either end. Next, fold the paper along the diagonal cuts to create a “K” shape. Assemble the truss by gluing the diagonal and vertical members at the joints.
Remember to choose a truss design that suits the type of paper and glue you are using. Different designs will have different strengths and weight-bearing capabilities, so choose wisely. Once you have decided on a truss design, proceed to the next step: construction. For more information about what type of glue to use, check out our article on what glue to use on graduation cap.
Construction
Constructing the base of the bridge requires precision and patience. Here are the steps to build a sturdy base:
Step 1: Cut the truss design
Using a sharp pair of scissors, carefully cut out the truss design that you have chosen. Be sure to use measurements that are accurate and consistent to ensure a stable structure.
Step 2: Fold the truss sections
Lay the cut-out truss designs on a flat surface and fold each section at the designated lines to create the “W” shape of the trusses.
Step 3: Glue the truss designs together
Apply a thin layer of glue to the surface of the folded sections and attach them together to form the full truss. Repeat this process until you have enough trusses to span the length of your bridge base.
Step 4: Attach the trusses to the foundation
Using wood glue or any sturdy adhesive, attach the trusses to the foundation that you have created in the previous steps. Be sure to follow the truss spacing and placement guide to ensure the stability of the bridge.
Step 5: Add diagonal cross bracing
Cut diagonal sections from the scrap paper and glue them to the trusses. This will provide additional stability to the bridge structure.
Step 6: Reinforce with toothpicks (optional)
If you want to add some extra support, insert toothpicks into the center of each truss and glue them to the foundation. This will help keep the trusses upright and stable.
By following these steps, you will have a solid and secure base for your paper bridge. In the next step, we will attach the deck to the base to complete the bridge.
Attaching the Deck
After constructing the foundation and truss of the bridge, it’s time to move on to the next step of the building process: attaching the deck. The deck serves as the roadway of the bridge, providing a surface for vehicles and pedestrians to travel on. In this section, we’ll discuss the materials needed for the deck, as well as the construction process. By the end of this step, your paper and glue bridge will start to take on a more complete form, ready for the final touches.
Deck Material
When it comes to the deck material for your paper bridge, there are a few options to consider. The most popular choice is using cardstock paper because it’s thicker and sturdier. However, if you want to add more creativity to your bridge, you could also use scrapbook paper.
Scrapbook paper is a great option if you want to make your bridge look more unique and colorful. You can choose from a wide variety of designs and patterns, such as floral prints, animal prints, or even themed prints like superhero patterns. To use scrapbook paper, simply glue it to a piece of cardstock paper or cardboard for added support.
Cardstock paper, on the other hand, provides a stronger base for your deck. It’s sturdier than regular printer paper and can handle more weight. You can also choose from a variety of colors to match your design preference. When using cardstock paper, make sure to cut it to the appropriate size and shape for your deck.
Regardless of the material you choose, make sure to secure it onto the truss design properly. You can use glue or double-sided tape to ensure it’s firmly attached. If you’re interested in learning how to glue scrapbook paper to wood, check out this link for step-by-step instructions.
Deck Construction
To construct the deck of the paper bridge, you’ll need to follow a few basic steps. It’s important to start by cutting out a rectangular piece of paper to create the main deck of the bridge. You can use any type of paper, but something sturdy like cardstock will work best.
Once you have your rectangle cut out, it’s time to start attaching it to your truss system. First, apply glue along the top of one of your trusses, using a glue stick or a small brush. Then, carefully place the deck piece onto the glued truss so that it lines up with the edges of the truss. Press down firmly to ensure a strong bond.
Repeat this process on the other side of the truss, making sure that the deck remains level and straight. It’s a good idea to hold the bridge up and check that it isn’t sagging in the middle.
Next, you can add additional support to the deck by gluing on additional pieces of paper on either side. Cut these pieces to size so that they fit between the bottom of the deck and the top of the truss, and then glue them in place. This will add stability to the bridge.
To make the deck more realistic, you can add lines to create the appearance of planks or boards. Use a fine-tipped pen or marker to draw these lines onto the paper, making sure they’re evenly spaced. You can also add other decorative elements, such as paint or stickers, to give the bridge a unique look.
Constructing the deck of a paper bridge is a relatively simple process that can be completed with just a few basic materials. By following these steps and taking care to ensure that the deck is level and secure, you can create a functioning bridge that can support the weight of small objects.
Pro tip: For an even sturdier bridge, consider using toothpicks or other small wooden sticks instead of paper for the deck. Check out our article “How to Make a Bridge Out of Toothpicks and Glue” for a step-by-step guide.
Supporting the Bridge
As we move forward with our paper bridge project, the next step is to focus on supporting the bridge that we have built so far. A bridge, whether it’s made out of paper or any other material, needs strong and sturdy support to hold up the weight of vehicles, people, or objects passing over it. In this section, we will discuss how to create pillars that will support the truss bridge. So, let’s get started and learn how to construct the supporting pillars for our paper bridge project.

Pillar Material
When it comes to the pillar material for your paper and glue bridge, you have a few options to choose from. The material you choose will affect the overall look and stability of your bridge.
Toothpicks: Using toothpicks for the pillars is a great option if you want a bridge that looks delicate and intricate. However, keep in mind that toothpicks may not be strong enough to support a heavier deck.
Straws: If you want a sturdier option for your pillars, try using straws. You can use regular straws or thicker smoothie straws, depending on the size of your bridge. Cut the straws to the appropriate length and glue them in place.
Popsicle Sticks: Another great option for your pillar material is popsicle sticks. They are sturdy and can support a heavier deck. You can easily cut them to size and glue them in place.
Matchsticks: If you’re looking for a more unconventional option, try using matchsticks. They can add an interesting texture to your bridge and can work well for smaller, more intricate designs.
Keep in mind that the type of pillar material you choose will also affect how you attach it to the base and deck of your bridge. Consider the overall look you want to create and the sturdiness you need for your design.

Pillar Construction
Once the foundation and truss design are complete, it’s time to move on to constructing the pillars that will support the bridge deck. The pillars need to be sturdy enough to hold the weight of the bridge and any objects that may cross it. Here’s how to construct strong and stable pillars for your paper bridge:
1. Take four sturdy strips of paper and fold them in half to form a square-shaped base for the pillar. Use a small amount of glue to hold the folded paper in place.
2. Use strong glue, like Gorilla Glue, to attach four thin but sturdy strips of paper to the inside edges of the folded paper base. Make sure the strips are evenly spaced apart and create a square shape.
3. Create four more identical square shapes as described in steps one and two. These will be stacked on top of one another to create the full pillar.
4. Connect each square shape with a strip of paper that runs from the top of one square to the bottom of the next. Use strong glue to secure the strips and create a stable structure.
5. Continue stacking the squares and connecting them with paper strips until the pillar reaches the desired height. For maximum stability, consider using an odd number of square shapes so that the top square can be positioned in the opposite orientation from the bottom square.
6. To add decoration or extra stability, you can wrap the pillar in multiple layers of paper strips, or even paint it with craft paint.
With sturdy pillars complete, your paper bridge is ready to cross over any obstacle. Impress your friends and family with your engineering skills by building a paper bridge that can support the weight of small toys or even coins.

Once the bridge has been constructed, it is time to add the final touches and make it look presentable. Painting and decorating the bridge is an important step in this process. Here’s how you can do it:
- Prepare the Surface: You need to prepare the surface of the bridge before you start painting it. You can do this by sanding down any rough patches or edges. You can also use a piece of cloth to wipe away any dust or debris that might be present on the surface.
- Choose the Color: You have a variety of colors to choose from when it comes to painting your bridge. If you want the bridge to look natural, you can choose a brown color. If you want it to stand out, you can choose bright colors like red, blue or yellow. You can even mix different colors to create a unique look.
- Apply the Paint: Once you have chosen the color, it is time to apply the paint. You can do this using a small brush or a roller. Make sure that the paint is applied evenly to all parts of the bridge. You can apply multiple coats of paint if required.
- Add Decorations: After the paint has dried, you can add decorations to the bridge to make it look more appealing. You can use stickers, stamps or stencils to add different designs to the bridge. You can even draw designs on the bridge using a marker or paintbrush.
- Protective Coating: Once the decorations have been added, it is important to apply a protective coating over the bridge. This will prevent the paint from chipping away and keep the bridge looking new for a longer period of time. You can use a clear coat of varnish or a polyurethane spray for this purpose.
By following these steps, you can easily paint and decorate your paper and glue bridge, giving it a professional finish that will impress everyone who sees it.
