I just finished this bridge a few days ago after working on it on and off for 3 months. It’s a cable stayed bridge design made with standard round toothpicks and wood glue.
The bridge is 31 inches long and just under 20 inches tall. The main road truss is 2 inches by 2 inches, constructed of beams of laminated toothpicks.
Hi, I just wanted to share the excitement…by using ideas from your website (recommended by my son’s Cub Scout leader) my son Jackson and I were able to build a Popsicle bridge with approximately 125 sticks. It set a new record by holding 500 lbs. for about 15 seconds before breaking! Thanks for the great ideas…not bad for the first try
This is a popsicle stick bridge I built while in the last few weeks of my fall college semester. I used 924 popsicle sticks to build this bridge. This bridge was 5 feet long, 10 inches tall, and 8 inches wide. I had to sort through 2600 popsicle sticks to find enough usable ones. The first testing of the bridge consisted of 220 pounds worth of weights. The second testing included putting a piece of plywood on top of the bridge and me standing on it (170 pounds). We noticed that one end diagonal chord was bending tremendously, so I decided to call off any more testing until I could repair that one piece
These are the photos of a popsicle bridge that I made for a bridge building contest at my university in Spain. The weight of the bridge was 3.9kg, and the bridge held 700kg without breaking. This gives it an efficiency score of 180. The dimensions of underneath the arc are 90cm x 45cm.
Hey guys it’s me again, First Timer. Taking the critiques you guys gave, I rebuilt the bridge. This was going to a county Science Fair which I think is pretty cool considering I started learning about bridges about 2 months ago. The specs of the bridge are
Hey guys it’s me again, First Timer. I came up with a good way to practice bridge building either before or for the next competition and/or just to keep your bridge building skills good, whether it be science fair or science olympiad. It’s building different bridge designs with K-NEX, Erector Sets, and/or LEGOs. Most of you probably own one or more of the following and it really helps practicing basic truss design
Hello everybody my name is First Timer and I had to make a balsa wood bridge with theses specs: 40.5 cm long, 11-12 cm wide 13-25 cm high, must have a span of 26 cm, peek of the span must be at least 9 cm, and this bridge could weigh no more than 16 grams
Built by Bill H. Here is the email Bill sent me:I started making bridges about a year ago and have pictures to share with you. For the first bridge I used a set of plans that I found free on the internet from a guy who was in the army. The bridge plans were designed … Read more
This bridge is the Arthur Ravenel Jr. Bridge which is over the Cooper River in Charleston, South Carolina. It is North America’s largest cable stayed bridge. I got these photos when visiting family up there.
Pictures taken on October 5, 2006. This is only of the few historic bridges that is still in use. I am glad to have found it. The metal does not look in great shape, so I hope it sticks around for a while. More than that, I hope that when it is eventually replaced that … Read more
