On Angies List, there is no specific category for sales only, as opposed to furnishing and installing which would be Driveway contractors (both concrete and asphalt types).

Try googling a search phrase like this to find suppliers - putting in your town name instead of Knoxville - most decentsized towns have a street and highway supplier who deals in drainage products, guardrails, etc.

culvert supply Knoxville

Some (especially in rural areas) farmers co-ops and lumber yards also carry the most common sizes of culvert. Some lumberyards and many home improvement box stores also carry corrugated plastic drain pipe - though check the guidelines for burial depth as it commonly has to be buried a foot or so deeper than galvanized steel culvert. And don't forget the wingwall pieces - keeps fill out of the pipe, and also increases the flow capacity around 2 fold over just a bare pipe end sticking out on the inlet end. And don't forget compaction around the pipe - good plate compactor compaction under and all around a culvert roughly doubles the amount of load (think delivery trucks with construction materials or topsoil or concrete drive replacement readymix truck or such) a culvert can carry over one buried in loosely placed fill.

And don't forget good compaction of silty/clayey/topsoil material (typically 4 inch layer or such) all over the upstream (but NOT downstream) face of the fill around the culvert from ditch bottom to top of fill to keep water from infiltrating through the fill and bypassing the pipe, eroding out the driveway fill.

My recommendation - of course check with local road department on required roadside ditch pipe permit and minimum size (commonly 12 or 18" minimum, more with larger flow capacity ditches) - but I would never use less than a 12" culvert on a roadside ditch, and in an area like yours with heavy thunderstorm flash flooding, I would be looking at 18-24" minimum in many cases.
