Culvert pipe source?

[Gravy]

I've got to source some 2' or 3' culvert pipe to build a driveway over a drainage.
Probably want to do 10-20' length.

Wondering if you guys might have some recommendations?

Concrete vs. galvanized?

I know very little other than it seems galvanized is easy to get hold of up to 2'

I think 3' would be preferable for my project.

Contech in Ogden builds culverts. I sold their stuff for years in the Uinta Basin. I now work at a Carquest, but if I remember right, cost per foot wise, 24" and down is cheaper in plastic (hdpe) and 30" up is cheaper in galvanized. But it's been two years so I'm not sure how the market is now days.
