  • Overview

    Interstate 64 is West Virginia’s eastbound-westbound transportation life line. It crosses the Kanawha River four times in the state capital of Charleston alone. At one such location, the Division of Highways called for the construction of a new bridge to increase traffic capacity and improve traveler safety. But there was an added challenge: the design of the new bridge had to be completed without utilizing a single pier in the Kanawha River. Known for our long span experience, Modjeski and Masters was entrusted with designing the steel bridge alternative.
     
    Modjeski and Masters studied several steel alternatives, including box girder, truss, and tied arch bridge types. We then developed a steel bridge alternatives matrix to evaluate cost, aesthetics, and constructability. Working with the Division of Highways, our knowledgeable engineers helped identify the preferred steel alternative – a three-span continuous steel box-beam girder bridge. To span the river, our technical experts engineered a design featuring a record-setting 760-ft. dual box girder main span. Great in scale, yet elegant in form, the haunched girder design measured over 30-ft deep at the pier tops and 15-ft at the main span centerline. Modjeski and Masters developed a 3D time-dependent finite element analysis to check construction loading. In all, 70 load steps were used to capture construction loading effects, from steel erection to the specialized concrete overlay.
     
    In 2007, despite lower bid results for the concrete alternative, this girder bridge design captured the West Virginia Division of Highways Engineering Excellence Award for the Large Bridge Category. And our reputation for technical excellence is one of the reasons why the Division of Highways, like many of our long term clients, continues to expect great service from us.
