Hey, just want to start by saying I'm new here!
So:
My bridge that leads to my house is starting to get bad. It's the load-bearing boards that are bad.
Yep, funnily enough, they're using boards 70x200mm, I think it is now.
But now I'm considering replacing the boards before a car goes through.
Thinking about using some sort of beam. I've also thought about casting, but it seems like the time/cost would be more.
Give me suggestions. H, I or U beam, etc.
The bridge is about 6m.
Thanks for the answers
