Oregon State Highway Engineer (1932-1956). Proposed the trash rack solution at Warren Falls and advocate "advocated for the construction of what would eventually become I-84 in the Columbia Gorge, initially built as a “straightened” US 30 that bypassed or obliterated Samuel Lancaster’s visionary Columbia River."
...his assistant highway engineer was none other than Conde B. McCullogh, the legendary bridge designer whose iconic bridges define the Oregon Coast Highway.
McCullough designed several bridges along the Columbia River Highway, as well, yet he apparently passed on the opportunity to apply a more elegant design solution to the Warren Creek flooding problem. Otherwise, we might have an intact Warren Falls today, perhaps graced by another historic bridge or viaduct in the McCullough tradition!
