October 2012 - The Oregon Department of Transportation reopened and rededicated the 90-year-old Oregon City Arch Bridge after a $15 million rehabilitation project.


The project received many accolades, including a 2013 Oregon Heritage Award and the International Bridge Conference’s 2013 Abba G. Lichtenstein Medal for “a recent outstanding achievement in bridge engineering demonstrating artistic merit and innovation in the restoration and rehabilitation of bridges of historic or engineering significance.”


Conde B. McCullough designed the 1922 bridge as a steel plate through arch with a Gunite covering to protect it from the caustic emissions from nearby mills.
