    The Cooper River Bridge, designed by Howard Needles Tammen and Bergendoff (HNTB), is a major structure (opened 1992) in the I-526 Mark Clark Expressway in Charleston, South Carolina. More than a record span for the state (a main span of 800 feet and side spans of 400 feet), the bridge is emblematic of a new generation of truss bridges; trusses which are more aesthetically appealing and at the same time incorporate technologies which make maintenance easier and extend the bridge life.

    The bridge was completed for a cost of roughly $20 million and opened to traffic in 1992. The steel truss was fabricated by Pitt-Des Moines, Inc., and erected by John F. Beasley Construction Co. Construction engineering by Tylk, Wright and Gustafson of Matteson, IL.
