Recently picked up a couple of semi loads of brand new culverts ranging in diameters of 12", 15" 18", 21" 24", 30", 36" and 48". Lengths vary as do the prices. Please email with your needs and I will see what is available. Most of these culverts are in perfect shape and a few have some small manufacturing defect that won't matter once its in the ground! Great for driveways, field entrances, low flow crossings, etc.
