 The town of Wishram (then known as Fallbridge) was fortuitously situated at a location which made bridging the Columbia River relatively easy.It was possible to construct a bridge that had piers resting on normally exposed basalt rock above the waterfall during low water periods such that during periods of high water, when this stretch of the Columbia River became raging rapids, the piers supported a bridge spanning the entire flood.This bridge over Celilo Falls became known as the Oregon Trunk Rail Bridge or the fallbridge.
