Twin Bridges

During Super Mario World, the Twin Bridges are a pair of parallel bridges found in Dinosaur Land. Both bridges lead from Vanilla Dome to Cookie Mountain. One bridge, the Cheese Bridge, is smaller than the other and only has one level (near Soda Lake). The larger and higher bridge is the Butter Bridge, which is accessed by a secret path in Vanilla Dome and connects the two mountaintops. There are two levels on this bridge. The Twin Bridges, combined with Cookie Mountain, are the fourth world of Super Mario World. If Mario reaches the Secret Exit of the Cheese Bridge level, he will find access to Soda Lake, which in turn will lead to the third Star Road.
