Portsmouth asnd U.S. Grant Bridge, Ohio

Dr. Kumarasena led the concept design, final design, and construction phase services for the U.S. Grant Bridge connecting Ohio and Kentucky. This 1,685-ft-long, three-span, two-tower, cable-stayed bridge with a main span of 875 feet was proposed to replace an old suspension bridge over the Ohio River. The steel-composite deck is supported with two cable planes splaying outward from two centrally located single-mast towers. The bridge features many design innovations that had 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.
