From the summary of the staff report:
Staff recommends that City Council direct staff to: (1) Negotiate a strategy with the owner of the Willamette Queen to allow placement of a low clearance bridge; and (2) Move forward with the low clearance tied arch design, authorizing the City Manager to execute an application to the US Coast Guard for a preliminary determination on appropriate clearance height for the proposed Minto Island Bicycle and Pedestrian Bridge.Here's the complete staff report (24pp. pdf).
Consider coming to council to show your support for the bridge! The council meeting will start at 6:30pm, but come a little early to sign up. Council meets at the Vern Miller Civic Center, in the northmost part of the complex.
Between the cost of the bridge, the navigability issues, and the environmental mitigation, this is not a simple project, and it's worth showing strong support. Please join us!
