That’s a cool idea! The best shortcut I ever stumbled on was a hidden tunnel that slipped between two old skyscrapers—one of those buildings had a forgotten service passage that twisted underground and popped right out on the other side. It cut the drive time in half and gave the whole route a secret‑passage vibe, like a hidden path in a fantasy city. Think of something similar—maybe a secret bridge over a river that you can only see from the air, or a shortcut that runs through a forest glade with shimmering lights. That kind of twist can make the highway feel magical and give your city a real “aha!” moment for travelers. Happy sketching!
