The New Tacoma Narrows Bridge: Suspension System and Anchorage
The suspension system of the New Tacoma Narrows Bridge consists primarily of two (2) main cables and 132 vertical suspenders. Each cable is constructed of 8,816 high-strength steel wires, resulting in an overall cable diameter of 20-1/2" (521 mm). These cables pass through splay saddles and divide into 19 strands each. The strands are held by strand shoes anchored with high strength anchor rods deep into the anchor block. The suspender groups consist of either two or four lengths of rope arranged with four rope terminations at deck level. The ropes are generally 1–5/8" (41.3 mm) diameter zinc coated steel structural wire rope. The suspenders are attached to the main cable by way of cast steel cable bands and the main cable is supported at the towers and anchorage splay points by cast steel saddles. The keyed-in gravity anchorages located on both ends of the bridge resist the pull of the main cable tension. The anchorages are constructed of cast-in-place reinforced concrete and each anchorage contains approximately 20,600 CY (15,750 m3) of concrete. The roof of the anchorage also serves as the roadway for vehicles traveling onto and off of the bridge. The roadway slab is supported by pre-cast I-girders with room for a lower level roadway that may be added in the future.
