3 ton-31' Bridge Span Revised for Steel

[deanfitz]

After measuring & observing the site with much review and sitting down with construction superintendent we came up this revised edition of my creek bridge project.
The span will be 31' from inside to inside of bridge piers. We will embed the heavier (39"L x 12"H x 10"W x 53lbs a foot) steel i beams into the cement footers with a center angle embedded as well. Cross angles will be welded 5' 2" apart for a total of 6.
The I beams will be put into place and supported after the holes are dug, then will build form around top 4' of hole to enclose the beams & center angle into the cement footer. Sounds easy (Not)...but will probably be easier and less expensive than previous versions of this planning.
We are working on a draft drawing.

In your other post, I thought you said the beams would be W12 x 30 lb per foot. Going to a 53 Lbs/ft Is going to add a good bit more strength.

Just wondering if you have decided how far appart the beams will be?

And what you have decided for sure on the decking?

Yes, LD1 I called P&W, the beams that are 39' Long are 12"x10"@53lbs a ft.($1,708.00 for 2) The bridge guy told me, it would be worth the extra $$$ to go this route. Build for the future. I think this bridge will support a decent size load once done.

FOR FURTHER UPDATES ON THIS PROJECT, I'LL BE MOVING THIS THREAD INTO THE PROJECTS SECTION.

Thanks, Dean
