Today’s Morrison Bridge, completed in 1958, is actually the third Portland bridge to carry that name. The bridge shown here, a swing span bridge built in 1887, was Portland’s first bridge over the Willamette River and the longest west of the Mississippi River. The second Morrison Bridge, also a swing span, was completed in 1905. At that time it actually terminated on the west side at Morrison Street, as shown here (the present bridge lands between Alder and Washington).
