The Pudding River Bridge is a thirteen span bridge consisting of 12 reinforced concrete girder approach spans and a single 120.7-foot steel through tied arch. The bridge was constructed utilizing a technique that engineers today would call accelerated bridge construction. The tied arch was constructed beside the older bridge and the slid into place while the old bridge was slid out the opposite side. This technique limits the impact on traffic during bridge construction of the bridge.
