Nanpu Bridge Interchange

The Nanpu Bridge helped Shanghai kick off its efforts to become one of the world’s largest cities. The bridge is one of the spans that connects older Shanghai with the newer Pudong area, negating the need for slow and tedious ferry trips. The bridge’s multi-lane interchange is part "spaghetti junction," part dizzying roller coaster. It spirals between the bridge and the ground, requiring vehicles to make two orbits before even reaching the exits for city streets and highways.
