Weld some more supports on it. Wouldn’t take long

What he should do is get a 30ish ft flat bed trailer to lay across there. That’ll take care of it.

I would keep in mind that this is a highway design with enough safety factor built in for the general public’s safety with an additional safety factor built into the load capacity of the beam. If you’re using it occasionally for personal use I think you’re fine. If you’re it for a regular haul road with several trucks per day for a long period of time I would reinforce with a center pier.
ETA I don’t think it’s a coincidence that the calcs came out almost on the money.

I wouldn’t want any video if this thing goes bad, and ends up in a law suit.

I stayed at a Holiday Inn Express last night. I say yes.

Going to derail this a bit, no colors, any chance a fellow OB'er could get a doe hunt this year? Would like to get my old man (60+) on his first ever.

Have you considered stacking several ice chests on each other?

We are about through with this little creek crossing. You want me to send them your way in about a month.

These engineers would wet their pants at what they drive tank trucks across off rock road in plaquemine.
More weight. Same layout. Only... No steel

I'm guessing it will take 3 years to recover. Probably half the hardwood sawmills that I know of are idled or have gone out of business all together.

I like it. Gas it

You've been given adequate advice from a structural standpoint of yes it could hold the weight, however it will break on you at some point.
Now from a soils standpoint, you are going to have settlement on both end of your bridge that may result in the on/off not being at an angle that the truck can safely traverse.
Based on the picture you provided of the side you placed concrete on it appears that you have a roughly 12' by 7' foundation. Assuming you are in Mississippi and you are in Yazoo clay that had standing water when the concrete was placed, you have a bearing capacity of 1,500 psf on the high end. With an area of 84 SF, you have a bearing capacity of ~126,000 pounds. That is a bit light for my liking. With 4 W12s on the other side, your capacity is non-existent. I'd make sure I had a wench.

Hard No.
I assume those girders are W12x40 wide flange by your definition. That beam has a 5,000lb max load at 26' span and has no rated load at 30' span.
That means if your 50,000lb load is divided between two wheel sets and means 25,000lb per girder, you are 5x the limit at a 26' span. Again at 30' span as you describe there is no rated load.
Dont forget your trailer is probably 8-10k lbs and your tractor is another 15,000+.

I wouldn't want to be underneath this bridge when the theory is tested.

You guys are way overthinking this, it will absolutely make it across. No doubts.

The main thing bothering me now is that jagged edge of uneven planks - I would have to snap a chalk line and square that up.
