Steel culverts

If its for a driveway the county provides them, idk about the installation though.

If it's next to a public road, you might want to call the county or city. Putting one in a public road right of way or easement might open a potload of liability issues.

Call the county, some counties will install the culvert if it is on their right of way for a driveway.
