ecmn | I did the pile driving and coffer dams and then help out with rebar and concrete as I could for the Drayton Mn ND bridge
Amazing how much stuff went into that thing, the big pier in the middle took 1000 yards of concrete, 120klbs of rear.
Depending on your frost levels I would dig out a good endbutment for each end, the top of the butment would be road surface and then an L shape for the beams to sit on.
After looking at the old bridge on how much the earth moves over time. | |
