When the original US Grant Suspension Bridge over Ohio River was built in 1927 replacing a ferry system that existed at the time; it opened up a new era at this key crossing point for people and commerce between Portsmouth Ohio and adjoining South Shore, Kentucky. Those who saw it first hand some 70 years ago still remember the transition. After nearly eight decades of service, the original bridge was found to be functionally deficient, too costly to maintain and impractical to upgrade by the Ohio Department of Transportation, and the historic bridge was removed in 2002 to make way for in-line replacement by a cable-stayed bridge. The new bridge not only provides higher functional standards with its wider roadways with generous shoulders but also improved river navigational conditions by virtue of its longer span. The new bridge, through this form following function design, has successfully met the Department's desire for an economical bridge providing higher level of serviceability with aesthetic appeal.

Structural Engineering International (SEI), the quarterly Journal of IABSE, published since 1991, is the leading international journal of structural engineering dealing with all types of structures and materials. SEI offers its readers a unique blend of short profiles on recent structures, and longer, in-depth technical articles on research, development, design, construction and maintenance. Articles are written by practicing engineers and academia from around the world and reflect the high standards of IABSE. IABSE Peer Review stamps are given to papers that have passed through a highly selective review process and demonstrate a significant contribution to the state of structural engineering knowledge.To recognise contributions of the highest quality, an Outstanding Paper Award is presented each year.
