Bridge to Nowhere, Road bridge in San Gabriel Mountains, California.

The structure crosses the East Fork of San Gabriel River in a steep canyon and rises about 120 feet (37 meters) above the water level. The concrete arch stands isolated between rock walls, surrounded by boulders and rushing water.

Construction began in 1936 as part of a road project along the East Fork intended to connect remote settlements. The 1938 flood destroyed the planned roadway and left the completed structure without access.

The name arose after devastating floods left the structure suddenly without connection, stranded and useless in the riverbed. Today visitors wade through water to reach it and use the arch as a destination for day trips and photo stops.

Reach the bridge on a 10-mile (16 km) round-trip hike along the East Fork Trail, which crosses the river at least six times between the trailhead and the bridge. The route is rough in places where washouts have occurred, and the riverbed is dry for much of the year. The San Gabriel Mountains Trailbuilders maintain the trail under US Forest Service supervision.

A company operates bungee jumps from the arch and is the only commercial facility of this kind in Southern California. The jumps take place directly over the river with free fall through the open airspace beneath the structure.
