It is being considered for replacement because:
This effort will build upon these previous efforts.
This effort will include identification of historic properties within the project area through field survey and background research; assessment of potential effects to historic resources that are identified; and the resolution of adverse effects to historic resources, if needed. These efforts will be conducted with consultation from the Oregon State Historic Preservation Office, project stakeholders, and the general public. A Historic Resource Baseline Report has already been conducted and will inform further identification of historic properties. Additionally, a revalidation will occur for the previously-documented Corvallis Downtown Historic District which has the potential to be affected by the project and features resources not situated within the project Area of Potential Effect (APE). The public is encouraged to submit historical information for resources within the APE and within the potential historic district.
Once the prudent and feasible alternative is chosen pursuant to Section 4(f) of the Department of Transportation Act and design efforts are underway, the process of assessing effects to properties that have been determined eligible for listing in the National Register of Historic Places (NRHP) can begin. Where possible, avoidance and minimization of impacts to eligible resources will be incorporated. ODOT will consult the State Historic Preservation Office, project stakeholders, and the general public on all findings.

The previous alternative analysis done in the 2005 Bridge and Roadways Concepts Report took a look at a wide range of alternatives. Yet recognizing that work is almost 15 years old and per the requirements of the USDOT, which insures that a current and relevant set of alternatives is considered whenever there is potential for a removal of a nationally significant historic bridge, ODOT is validating the conditions, assumptions and analysis that led to those alternatives – including the following:
With the utilization of federal funds, this project requires compliance with Section 106 of the National Historic Preservation Act, a procedural law that requires agencies to consider the effects on historic properties. A Bridge Repurposing Study will look at the alternatives for use of the existing bridge.
This Bridge Repurposing Study investigates the need for a new bridge and the possible outcomes of the existing bridge, should the City or other 3rd party choose to take ownership of the existing bridge at its present or relocated location. Additional project alternatives not listed in this document and not directly related to City or 3rd party ownership of the existing bridge are being concurrently examined or revalidated.
The three alternatives presented in the Bridge Repurposing Study are:
You can learn more about each of these three options on the following pages.
Construction: Approximately $12 million
Annual maintenance: Approximately $150,000
Five theoretical locations in the city were considered for cost estimating purposes. The actual future location would need to be determined by any future owner.
Along with the cost of moving, the bridge spans would need:
Construction: Estimated between $7 million to $10.2 million (including a temporary work bridge and removal of the existing bridge’s underwater piers and footings), depending on the new location.
Annual maintenance: Approximately $145,000

If demolition of the existing bridge is identified as the appropriate course of action, the cost of removing the existing structure will be incorporated into the construction package of building the new bridge. The anticipated length of time to complete demolition work is less than one year.
Demolition: Over $4 million (mobilization, work bridge construction, debris containment measures, and removal of bridge components)
Annual maintenance: $0
