Project Location: State of Montana, United States
Client: SEFBO Pipeline Bridge, Inc. - Humble, Texas
Dates: April 2002 - December 2002

Cable-suspended bridges of several different pylon configurations were evaluated for spans varying from 130 feet to 400 feet and for two different sizes of pipelines. The pylons consisted of tubular steel and wide flanges. End supports of the cables varied from backstays to stiff steel elements, based on allowances from right of way. Foundation varied from drilled shafts to large mats, according to soil profiles, access, and local subcontractors. Deatils were provided for lateral cables to resist wind loads and for detailing of the suspension system (strands, ropes, sockets, clamps, clips, clevises, and pipe seats).
