'''Cape Creek Bridge''' is an [[arch bridge]] that spans [[Cape Creek]] in [[Lane County, Oregon]], United States. The bridge carries [[U.S. Route 101 in Oregon|U.S. Route 101]]. Opened in 1932, it was designed by noted bridge engineer [[Conde McCullough]] and built of reinforced concrete by John K.

The Cape Creek Bridge has been impressed-current [[Cathodic protection|cathodically protected]] (ICCP) from [[corrosion]] since 1991.
