The Celilo Bridge was built near the site of Celilo Falls in 1912. The bridge was originally a fixed span structure, but a swing span was added during the construction of the Celilo Canal which provided marine passage of the falls. In late 1950ís a vertical lift span was added as a part of the construction of The Dalles Dam which flooded the canal and the falls in 1957. The swing span remains in place but has not been operational since the lift span was installed. The bridge consists of six fixed span through Parker trusses, one vertical lift span, one swing span and many plate girder approach spans.
