in front of the house we have a river over which we built a bridge three years ago. the water has visibly dug during this time and we fear that it will destabilize the bridge over time. we were proposed two solutions and we don't know which would be more efficient. the first - gabions (like a coiled fence wire) placed on the bottom of the river at the foot of the bridge and then loaded with gravel. the water level would rise by about 30 cm, it's a bit scary when we think about the rainy seasons. the second solution - 24 concrete slabs to be placed on the bottom of the river and which the water will load (under them) with mud, gravel, and leveling the surface. does anyone know what would be a better solution? thank you!

Hi!
I'm working on a project that requires me to model an existing structure and ive selected the Shenandoah River Bridge in West Virginia.

Does anyone know the dimensions of the steel members of the bridge, or where i can find them?

Thank you!!

Bridge in incheon Korea. Always pass it and always wonder if one of the white supports snap the whole thing collapses

Does it have any lights on it, or is that whole stretch of road just pitch black at night? Odd question hope its okay. ;;

hey everyone, im in high school and for my engineering class we are to build a bridge and the person whose bridge holds the most gets an A for the semester, i really need that A so im coming here for advice. the span is only 15” bridge is to be 16” long 4.5” tall and 2-4” wide. using 1/4” birch plywood for the members and making gussets out of cardstock to go over the joints. my first thought was an arch bridge but all the pieces have to be straight so scratched that idea, my next one was to do a regular warren truss bridge but instead of 4 sides take the top off and make it a triangle all the way through so it cant have a blow out on the sides as easy. would this give me an advantage? the record so far is 200 something pounds so if i could somehow get 300 pounds out of the little bridge i would be happy, pm me with any advice or ideas!

For instance the key bridge collapse. Biden vowed to build back better and will use tax payer dollars to build a state of the art bridge but then turn around and charge us to drive across it (tolls). That's not right. I've crossed that bridge many times along with many other people. I didn't mind paying a buck to cross it because that could be used to help maintain the bridge. But they increased it to 4$ one way. But they have eliminated all the toll workers and implemented a.i to snap your tag and send you a notice to pay. Since you don't have to pay the workers and the benefits along with them workers it is now more efficient and they save alot of money so you would think it shouldnt cost that much to drive across it. Remember the tax payers paid for it in the first place. Equivalent to paying cash for something and then having to pay each time you use it. Agree or disagree? Wtf?!?!

This should be fun for any engineers:

I have to build a bridge for my class using around 50 popsicle sticks each of them being 4 1/2 inches, 25 rubber bands (in case I need them), gorilla glue, and it must be 16 inches long. My teacher is going to put 40 pounds worth of dumbbells in a bucket which will hang from the bottom of the bridge. What type of bridge will be able to hold 40 or more pounds the best knowing that bridge just needs to be able to hold the bucket hanging from below it? Thanks for helping for the people who do…
