How Much Does a Driveway Culvert Cost in Alabama?
Angi, a national cost guide, puts a professionally replaced driveway culvert at $1,000 to $9,000. It puts the average near $4,500. Its paving guide gives a tighter $1,500 to $5,000 for a culvert crossing from the street to your property.
These are market numbers, not our price list. Pipe length, size and material move the total, and so does what the road office asks for. We put in driveway culverts and ditch drainage across North Alabama, with rock set over the pipe.
What does a driveway culvert cost?
Guides give one number for the installed job and a second for the pipe alone. Here are the market figures we found.
| What was priced | Market figure | Source |
|---|---|---|
| Culvert replacement, installed | $1,000 to $9,000, about $4,500 average | Angi |
| Driveway culvert from the street to your property | $1,500 to $5,000 | Angi paving guide |
| Culverts or drains on a gravel driveway | $500 to $2,000 | HomeGuide |
| Plastic pipe, a 24 x 20 foot length | $700 | Angi |
| Aluminum or galvanized steel pipe, a 24 x 20 foot length | about $800 | Angi |
Angi says its installed price may or may not include stone or rock to line the ditch. It usually includes resurfacing the part of the driveway that sat on top. Ask that any estimate spell out both.
What moves the price of a driveway culvert?
Angi ties the cost to culvert length, pipe type and driveway material. In North Alabama, the road office may set the first two for you. Cullman County calls for a pipe at least 20 feet long and no more than 60 feet unless approved. Lawrence County’s office sets the length.
Size comes next. Angi says a driveway pipe is typically 10 or 12 inches across. State highway rules start higher: ALDOT’s minimum side drain pipe, the pipe under a driveway, is 15 inches. ALDOT regions can require 18-inch pipe. Buy pipe only after the road office names the size.
Which pipe material makes sense for a driveway?
Angi lists four common culvert materials: aluminum, galvanized steel, plastic and concrete. Galvanized steel is strong and suits heavy traffic, but it can rust and form weak spots. Aluminum and plastic do not rust, though neither is as strong as steel.
Plastic pipe is light and easier to install, which Angi says suits low-traffic drives. Concrete is durable and suits heavy traffic. It is heavy to handle, and cutting it takes extra machinery. Lawrence County accepts new concrete, HDPE (high density polyethylene, a plastic pipe) or corrugated metal pipe.
What do end sections, headwalls and rock add?
On a state highway, ALDOT requires sloped end sections or sloped paved headwalls on pipes under drives. A sloped end section is a manufactured pipe piece that fits the end of the pipe. A paved headwall is concrete work, and we do not do concrete. If the permit calls for one, plan on a concrete contractor for that part.
The guides we checked gave no separate market price for end sections or headwalls. Ask for them as their own line on any estimate. We set rock over the pipe and build the drive back over it. For what the rock itself runs, see our Alabama gravel driveway cost guide.
Should you repair or replace an old culvert?
Angi says a rusted-out or damaged culvert is generally not worth repairing. Replacing it takes less time and will likely last longer than a repair. Angi also says a new culvert lasts 25 to 50 years.
Pulling the old pipe is part of a replacement. We dig it out with the trackhoe, and our dump truck hauling takes the spoil and old pipe away. On a state highway, ALDOT puts the cost of replacing the original installation on the property owner.
Who permits a driveway culvert in North Alabama?
The permit is your paperwork, and you file it with the road office. Who you call depends on the road your drive meets.
- State or US highway: ALDOT handles it. Every ALDOT permit application starts at the local district office. A driveway onto state right-of-way takes Form BM-111, which covers the pipe under the drive. The applicant pays every cost of the turnout.
- Morgan County road: Call the Morgan County Highway Department or the County Engineer’s office. The county says its driveway permit is not optional.
- Lawrence County road: Get the permit and have your pipe delivered. The county then issues a work order to install it. The permit is good for 90 days.
- Cullman County road: Mark the entrance. The county inspects it, tells you the pipe size, then inspects the pipe again once it is in. A pipe put in wrong or without a permit can be removed. Since late 2023, residents arrange their own installation, and the form asks who is installing.
- Inside city limits: Ask the city.
- Any other county: Call the county engineer. Ask the size, the material and who sets the pipe.
Do you need to call 811 before the pipe goes in?
Yes, because setting a culvert means digging. Contact Alabama 811 at least two to ten full working days before digging starts. The service is free for all users.
What about a culvert on a private drive?
A long private drive often crosses a ditch or a branch. A culvert there is work we do too, along with the driveway grading on each side. Check with the county engineer before work starts, since the rules change from county to county.
How does Precision Excavation put in a driveway culvert?
We lay the pipe in the ditch line and set rock over it. We cut new ditches or clean out old ones so the water has somewhere to go. Then we build or regrade the gravel driveway behind the pipe. Our dump trucks bring the rock in and carry the spoil out.
