The reason I say temporary is that we want to use it, as is, immediately but improve it later as weather and time permit. We would like to do this with the least impact on the stream and avoid putting in a giant culvert. We would also like to use the recycled steel and other materials we have available but that would be impossible if we get the local government involved. They claim to be green but they seem to over engineer everything which leads to waste and destruction. So we will build a "temporary" 30 year bridge. That way we are not doing anything illegal and we are reducing the impact on the stream. It is having enough of a struggle with the increased flow as it is.

Load wise, it would be important that delivery trucks could use it, but for now the Previa at 4000 lbs loaded would be the max. I will probably add the side trusses and a centre I beam later so it can carry trucks.

The tubes are oriented with the 5" vertical and are already capped. I will create some kind of pads to raise them up and keep them dry soon.

I'll take some pictures so I save a lot of explanation suffice it to say, there is room for the water to go now and it's very unlikely that it would ever touch the new structure.

If we get the local government involved, it would have to wait till spring in any event so we need a temporary solution

I would assume it to be mild steel to be safe, but I will do a spark test later to see if it's structural grade. They were used in a large building previously, so I would think they are structural grade but I don't know.

I was just reminded of the most important load requirement: Fire trucks.
