This bridge today sits right next to the Lewis and Clark Viaduct. Together these two bridges carry a freeway today, but originally, the Intercity Viaduct stood alone, and functioned as a major city crossing. Originally a single deck deck truss, ca. 1930 the bridge was converted to allow a single lane of traffic that passed through the truss on a lower deck, making the bridge a double-deck design. Today, the lower deck has been converted into a trailway.
The main double-deck truss spans are impressive, and their subdivided Double-Warren truss configuration is uncommon. The approach system, particularly south of the main spans, is impressive for its length as well.
