I-84 at 15 Mile Creek Bridge Replacement | The Dalles , Oregon

This replacement of a bridge spanning a 60-foot deep canyon required a detour structure, a demolition containment platform to protect the creek and heavy temporary structural supports for the existing bridge which supported traffic while half of it was removed. The new structure was built in two stages so that the original alignment could be maintained. A unique component of this bridge is the decorative panels suspended from the outside edge of the structure which are similar to those on other historic structures in the columbia River Gorge.
