Rope-strand cables support 1,207-ft. Suspension span
New method of stringing wire-rope cables for St. Johns bridge, across Willamette River at Portland, Ore; two main cables, 16 3/4 in. in diam, consist of 91 prestressed 1 1/2-in. galvanized wirebridge strands, each, in turn, made up of 51 wires varying in diameter from 0.100 to 0.196 in. and aggregating cross-sectional metallic area of 1.337 sq in.
