Oldiskool - 5/20/2019 20:47 Located in Minnesota or the Midwest. New or Used must be at least 20 feet long. Seems like most suppliers stop at 36 inches. Thanks! Talk to TrueNorth Steel - Culvert maker in Blaine (and other locations around the Midwest). https://truenorthsteel.com/drainage-culverts/ Won't be cheap, but they make all sizes up to 8 ft if I recall. Another consideration . . . . . if elevations would allow - shipping container with ends removed ? $1200 - $1500 for 20fter. Located St Cloud/hwy 10 area | 
60" inch culvert
