With the Bridge of the Gods toll bridge spanning the Columbia River above the Bonneville Dam, Stevenson acts as a sort of "twin city" to Cascade Locks on the Oregon side. Tribal legends and the geologic record tell of the original Bridge of the Gods, a substantial landslide that occurred here sometime between AD 1000 and 1760, briefly linking the two sides of the gorge before the river swept away the debris. The landslide's steel namesake now leads to tiny Stevenson, where vacationers traverse the quiet Main Street, planning excursions to nearby Mt. Adams or Mt. St. Helens. Washington's Highway 14 runs through the middle of town, and since the cliffs on the Oregon side are more dramatic, driving this two-lane highway actually offers better views.
