Design
The Seufert Viaduct was once part of the Columbia River Highway leading east from The Dalles. The bridge is a concrete stringer structure with arched fascia walls that give the bridge an arch appearance. The bridge also received many of the signature Conde McCullough architectural details such as inset bush-hammered panels and aesthetically pleasing rails. Though not technically designated as part of the Historical Columbia River Highway the bridge was built on the historic route just east of the present day designated area. The bridge is very similar to the Mill Creek Bridge also located in The Dalles.
