West Monitor Bridge
The West Monitor Bridge is representative of a common bridge type. It's riveted steel cylinder piers supporting the truss remain intact. The Puget Sound Bridge and Dredging Company built this two-span steel pinconnected Pratt truss in 1907. The bridge is long and wide. It uses two steel spans over the river with a timber trestle on each bank. The trusses have seven panels, resting on concrete filled riveted steel cylinder piers. In the early 20th century, this was an economical design. The bridge supports a timber deck which is wide, curb to curb.
