NOT TRUE. The strength to weight ratio for balsa is excellent. My company had a bridge building contest for engineers week. My bridge weighed 3.5 oz and held 718 pounds (2nd place). first plast was a little heavier and held over a thousand.
The best design depends on how the bridge is loaded, what dimensions must the bridge span and what restrictions there are (eg bridge weight and balsa stick restrictions).

Try making a bridge with balsa wood
A bridge made out of balsa wood and is an often used educational project.
The maximum weight that a balsa wood bridge can hold depends on its design, construction, and the quality of the materials used. Generally, balsa wood bridges can hold anywhere from a few pounds to several hundred pounds, depending on these factors.
the best way to build a balsa wood tower is to use as many triangle design as you can.
Yellow carpenter's glue.
Gather materials: balsa wood strips, glue, ruler, and scissors. Design your bridge on paper, considering length and width. Cut balsa wood strips to desired lengths using scissors. Glue strips together to form trusses and supports. Allow glue to dry before assembling bridge. Connect trusses and supports to create bridge structure. Test bridge for strength and make adjustments if needed. Add extra support if necessary. Finalize design and ensure all parts are securely glued. Test bridge with weights to ensure stability.
To cut balsa wood with a Cricut Explore Air 2, you will need to use a deep-point blade and adjust the settings on the machine to the appropriate thickness of the balsa wood. Place the balsa wood on a strong grip mat and secure it in place. Then, load the design into the Cricut Design Space software and follow the instructions to cut the wood. Be sure to test the settings on a small piece of balsa wood before cutting your final design.
Balsa wood can be effectively utilized in bridge construction by using it as a lightweight material for the bridge deck and support structures. By carefully designing the bridge to distribute weight evenly and reinforcing critical areas with additional materials, a sturdy and reliable bridge can be built using balsa wood. Additionally, proper maintenance and regular inspections can help ensure the longevity and safety of the bridge.
I use TiteBond 2 for balsa wood.

1 - First you must specify the length and width and height of the bridge. 2 - Make a map of the bridge. 3 - to draw maps of various parts of the bridge. 4 - Put the paper on balsa wood and cut wood. 5 - cut wood with wood glue to attach. 6 - be careful when designing a bridge where there is more power to choose the stronger of the wood.
