The Sellwood Bridge Community Advisory Committee will weight the criteria they will use to recommend a structure type for the new bridge at a meeting on Monday, July 26 from 5:30 pm to 8:30 pm at SMILE Station, 8210 SE 13th Avenue.  Meetings are open to the public and include time for public comment. 

Examples of criteria the committee will use include aesthetics/user experience, cost, construction time, constructability, impacts to social and natural environments, sustainability, seismic performance and maintainability.  At the meeting the committee will assign weights for the different criteria categories to establish their relative priority.  The meeting will include a report from a bridge technical team on recommended criteria weighting from a technical perspective. 

In September the citizen committee will recommend a preferred structure type for the new bridge.  Options include a steel or concrete box girder, steel plate girder, delta frame, deck tied arch or deck arch (in steel or concrete), extradosed, or through arch (in steel or a concrete/steel hybrid).  The public can see sketches of these structure types and share their opinions in an online survey through August 8 at www.sellwoodbridge.org.  

A preferred alternative that identified the location, cross section and interchange type has been recommended for the replacement bridge.  Design decisions will not be made until after the federal government approves the project’s Final Environmental Impact Statement. A Record of Decision by the Federal Highways Administration is expected in late summer.  Design work should begin in late 2010, with construction likely to start in 2012, if funding can be secured. 

The advisory committee includes local residents representing different project stakeholder groups.  Members represent associations for neighborhoods, businesses, bridge neighbors, transportation modes that use the bridge, river users, and design professionals.
