Customer Question

I have a bridge that goes to my house on an island, I need to I find out how much weight I can drive across the bridge. I don't want to break it driving a dump truck across it. It looks like 3-4 steel I-beams under a wood top made of 2x12 laying perpendicular and bolted to the I-beams then there is 2 rowsteel of 2 wood 2x12 parallel to the i-beams over the 1st layer of wood. It's 25' long and 10' wide, I haven't got under the bridge to measure the steel because I haven't wanted to get in the lake, but I will.

Do you have a sketch you can post?

Customer: replied 1 year ago.
I will get pictures in the morning, and I will measure the beams. I'd do it now but it's late.

Thank you. I'll look for it tomorrow.
