A one-year study to identify the financial and traffic impacts of constructing a bridge across the Willamette River at the location of the Canby Ferry, scheduled to be completed by the end of 2018
The Canby Ferry, operated by the Clackamas County Transportation Maintenance Division, crosses the Willamette River during daylight hours from north of Canby to east of Wilsonville. However, it is not able to run when the river level gets above 70 feet and during other inclement weather, can only carry six cars at a time, costs motorists $5 per vehicle for a one-way trip and costs the county considerably more money to operate than it receives in revenue.
Since the Ferry both limits the number of people who can cross the Willamette River and uses money that could otherwise be spent on road maintenance, the County is evaluating the long-term financial and traffic impacts of six possible future alternatives for crossing the river at the same location.
- Canby Ferry – continue service
- Canby Ferry – discontinue service
- Bridge (no toll) – continue ferry service
- Bridge (no toll) – discontinue ferry service
- Toll Bridge – continue ferry service
- Toll Bridge – discontinue ferry service
Financial, engineering, planning and traffic experts will study various factors related to each of the six alternatives (feasibility analysis details). Public meetings are planned in June (to inform people about the project and gather input) and October (to share the results of analysis). The final report is expected to be presented to the Board of County Commissioners in late 2018.
At this time no decisions have been made on whether to build a bridge. The Board will review the results of study in late 2018, discuss the issue further and not move forward without public input. If eventually a decision was made to proceed with a new bridge, actual construction wouldn’t take place until after several years of outreach, planning and design.
More than 250 interested residents attended an open house on June 13, 2018 to learn about factors related to each of the six alternatives in the feasibility study. Materials used at the open house are available below.

The study of financial factors, potential traffic impacts and related factors will continue through the summer, and we plan to hold another public meeting in the fall to report what we’ve learned. The Board of Commissioners will review the study results in late 2018, and no further action would be taken without additional public input.

Feasibility analysis details
Cost Estimates for Alternatives
- Costs for future operations, maintenance and capital for Canby Ferry
- Costs to discontinue ferry operations
- Cost for development, construction, and maintenance for bridge: Conceptual plan and elevations for two bridge concepts, both to be located at the current location of the Canby Ferry and extend from top of bluff on the north side to top of bluff on the south side. The bridge concepts will be selected to provide low and high figures for costs and environmental impacts.
- Operating costs for three toll methods: manual, transponder and optical character recognition. Identify facility requirements and associated costs, information system requirements, staff/vendors, annual operating costs and administrative costs
- Identify roadway improvements that will be necessary to accommodate increased traffic and estimate cost for the improvements
Revenue and Traffic for each Alternative
- Future revenue and traffic assuming only continued operation of Canby Ferry
- Future traffic with the addition of a non-tolled bridge
- Future traffic with a tolled bridge, with tolls of various amounts to identify the relationship between cost and traffic. A financial forecast of expected toll revenues on a yearly basis will be developed for each toll scenario. Future traffic with highly congested conditions on I-5/I-205 will also be analyzed to identify maximum diversion.
Total Annual Costs
- Estimate future costs for the operation/maintenance of the Canby Ferry including capital rehabilitation and replacement.
- 30 Year Bonding Cost analysis incorporating all capital improvement costs for the bridge and associated facilities including annual debt service and financing costs, annual contribution to capital reserves, and increased cost for roadway operations and maintenance.
- 30 Year Annual Cost analysis for the toll collection system including annual cost for toll system operations, staffing, operations and maintenance. The analysis will be conducted for three alternative tolling methods in use today (manual, electronic and photo) to develop a cost analysis for the application of each of the tolling methods to the Canby Bridge, including the option for contracting for logistical/administrative support with other agencies in the Northwest.
- Analysis to identify roads and intersections in the surrounding area that will experience increased traffic due to the addition of the bridge and estimated increases in annual maintenance costs.
- Annual revenue minus annual costs for each of the six alternatives identified above.
- Prepare an outline of all steps to develop a bridge and implement tolling, including requirements for tolling by local governments under Oregon Revised Statutes, environmental review and permitting by state/federal authorities.
