Design
The Cape Creek Bridge is an example of an ancient bridge design combined with early twentieth-century use of reinforced concrete construction techniques. While reminiscent of Roman stone aqueducts because of its two tiers of numerous arches and columns, the 619-foot bridge incorporates in its design a 220-foot open-spandrel rib-type reinforced-concrete deck arch. At the time of the bridge's construction, the U.S. Bureau of Public Roads was completing a 700-foot tunnel through nearby Heceta Head, at the south approach to Cape Creek Bridge. Both undertakings were part of long-range plans to complete a highway along the length of the Pacific Coast. This section of highway presented engineers with major construction problems. It became known to many as the "million-dollar mile" because of its high cost.

Cape Creek Bridge
Posted May 30, 2009, by Linda C. Boyd (Lin4art [at] aol [dot] com)

I was happy to find this page with this bridge. I have always wondered about it and fasinated by it. I painted an oil painting of this bridge in 2005 from some photos I took when I lived in Oregon.

I also have it listed on my web site. If interested email me. As you can tell,I knew nothing about this bridge. Now I do,thanks.
