Conde B. McCullough and Upper Perry Arch Bridge
McCullough was instrumental in designing site-specific bridges that exhibited elegant arches and soaring heights. He promoted the idea that "architectural features and scenic considerations" factored into the selection of bridge type, and that if a bridge is plainly visible in side elevation, it should have a pleasing profile.
Good Design Draws Tourists
McCullough believed that well-maintained highways, with pleasing bridges, drew more tourists, who increased the consumption of goods and services and contributed to the all important gasoline tax receipts.
Saving a Legacy
Maintenance of the Upper Perry Arch Bridge decreased when nearby Interstate 84 bridges were constructed in the 1960s. Over time, primarily due to freeze-thaw cycles, the concrete deteriorated along much of the structure and the weight across the bridge had to be severely limited. ODOT considered replacing the bridge, but due to its historical significance it was decided to rehabilitate the bridge. Thus retaining one of two single arch bridges in eastern Oregon.
