Regular traffic will be permitted after 7 o’clock tonight, and the afternoon in the meantime is given over to parades, speeches, and loud cheers for the grater elbow room permitted trans-Willamette traffic and the opportunity for commercial development produced by this facility for rapid connection between East and West Sides.” The photograph accompanied a story headlined “County and State Unite With City in Bridge Dedication.” Image note: Photograph shows discoloration due to deterioration of the negative.
