Design and construction details are given for the Tanana River pipeline suspension bridge section of the trans-Alaska pipeline. The 1,200 foot span is the longest of 50 elevated crossings. Unlike the usual modular steel girder bridges, cable suspension was considered more appropriate for the Tanana River span. Specifications were needed to meet 100-mile-an-hour winds, temperatures from /sup -/70 to 100 degrees F., heavy icing, and seismic shocks as high as 7.5 on the Richter scale while supporting a 48-inch pipe. Assumed loading conditions were used in the preliminary design of major components and subsequent analysis by the Engineering ANalysis SYStem (ANSYS) Computer Program allowed confirmation or modification of details as the design progressed. Protection of fish spawning beds caused the only major construction delay, although final completion was on schedule. (DCK)
