Notes
Survey number HAER WA-86
Unprocessed field note material exists for this structure (N142).
Building/structure dates: 1916 initial construction
Part of building/structure is in Portland, Multnomah County, OR.
Significance: The original 1917 bridge represented an enormous financial and engineering accomplishment, shared by the counties of two states. It was designed by the renowned engineering firm Waddell & Harrington, leaders in the field of vertical lift bridge design in the twentieth century. The 1958 bridge was built as a twin structure to the original. The piers of this bridge were assembled from hollow precast segments, a (then) recently patented technique.
