If this historic bridge and tunnel weren’t here, what would it be like to cross Cape Creek?

Engineers building the Pacific Coast Highway in the early 1930s encountered an unusual challenge here at Cape Creek, a deep, offset gorge, carved over thousands of years by the power of sea and creek.

Famed bridge designer Conde B. McCullough, a State Bridge Engineer, used both old and new technology to meet the challenge. His Cape Creek Bridge design is similar to Roman aqueducts, with two lower viaduct sections supporting a taller, open-spandrel deck arch.

McCullough used a cutting-edge technology in this Roman-inspired design: steel-reinforced concrete.

"You can't help but wonder how in the dickens the great state of Oregon wants to make an expenditure like this to cross a little creek which isn't more than knee deep."
The Siuslaw Oar,
November 7, 1931
