The City of Oregon City has been conducting traffic volume studies since 1978. We have historical traffic volume counts from 1978, 1980, 1989, 1990, as well as more current ones. Any of our historic studies are available for review. Our most recent studies are available online (see below) and will be conducted every 3 years, or as needed.

If you have any questions about the studies or would like to view historical data, please contact Chris Dunlop at 503-496-1566.
