US Grant Cable-Stayed Bridge

Location: Portsmouth, OH (2006)

Owner: Ohio Department of Transportation (DOT)

Prior Experience: Sena Kumarasena

Bridges, Cable Supported Bridges

This 1,685-ft-long, three-span, two-tower, cable-stayed bridge with a main span of 875 feet replaced the old U.S Grant suspension bridge over the Ohio River at this location. The new bridge features a steel-composite superstructure supported with two cable planes splaying outward from the two centrally located single-mast towers. Sena Kumarasena, Ph.D., PE served as the Lead Engineer for the concept design, final design, and construction phase engineering services for the U.S. Grant Bridge connecting Ohio and Kentucky. The bridge features many design innovations that enhanced its economy, serviceability, aesthetics, and constructability. The bridge towers are supported by compact water-line foundations. The unique superstructure design is lighter and uses significantly less structural steel than typical steel bridges. The engineering services also included the development of an innovative existing bridge removal methodology that minimized disruption to navigation.
