William H. Natcher Bridge

This award-winning crossing connects U.S. 231 northeast of Rockport, Indiana with U.S. 60 northeast of Owensboro, Kentucky.


To help relieve traffic congestion and open the area for more economic development, the Commonwealth of Kentucky Transportation Cabinet—in cooperation with the Indiana Department of Highways and the Federal Highway Administration—selected WSP USA to provide preliminary studies and design, final plans, specifications, and cost estimates for a steel alternate cable-stayed bridge over the Ohio River. 

The constructed William H. Natcher Bridge consists of a 4,505-foot-long four-lane bridge with a 1,200-foot main span, two 500-foot side spans, a 1,345-foot approach on the Kentucky side, and a 960-foot approach in Indiana.We also provided other engineering services, including state-of-the-art hydraulic modeling and scour analysis of the total crossing, ship-impact analysis, seismic evaluation and analysis, and preparation of contract documents for the bridge, including the approach structures and the main-span. 

Innovative design elements also facilitated both construction and subsequent maintenance. According to James C. Codell, III, former Secretary of the Kentucky Transportation Cabinet, speaking at the opening ceremony, “The William H. Natcher Bridge is a magnificent structure. WSP identified our needs and exceeded our expectations.” In addition to other awards, Natcher Bridge was named one of the top ten bridges of 2002 by Roads & Bridges Magazine.
