Thanks everyone for the advise. From what I've learned I may come out better going with steel.
OK, heres what I have found out.
During flood periods the whole area(app.1/2 mile from river) is under water in extreme high river. Heavily wooded, so the current is moving slow...maybe 1 mph. I have found 2 used 39' I beams measuring 12"Hx6 1/2"W x.46"T @ 30lbs a foot. Price-$936.00 w/o shipping. Will haul myself from P&W Ind. 30miles away from me. I'm thinking concrete footers at 12'w x 8'd x3' thick= 8 yds cement(1 truck)=around here$690.00 P&W also has 4" angle iron reasonably priced.
I can maybe use creosote boards to plank since sheet/grating steel is high priced. I can burn anchor holes in I beams for plank boards before hauling to bridge site.
This is a COMBINED VIEW of top & side design to give you a idea of what I'm thinking.
