If your sewer pipe ever clogs, never blame the bridge. It’s not the bridge’s fault you flushed a toy dinosaur. Also, keep heavy vehicles off your handiwork—a three-ton tractor will turn your bridge into matchsticks. That tractor will also make you cry.
But for foot traffic? For a flower pot and a casual stroll? Your bridge will last decades. And if it doesn’t, well, you’ll have a great story to tell while the plumber digs up your yard. “I once built a bridge over a sewer pipe,” you’ll say, sighing as the smell drifts up. And everyone will laugh, because they’ve all made questionable decisions too. Welcome to the club.
