Single Issue: A New Single-Tower Cable-Stayed Bridge Between Ohio and Kentucky

The new Ironton Russell Bridge across the Ohio River will be one of the longest single tower cable stayed bridges in the world. The bridge will link Ironton, Ohio with Russell in Kentucky. The total length of the bridge is 781 m and it consists of a 57 m long river crossing with a 205 m long approach on the Ohio side. . This article describes some of the numerous contradictory constraint that had to be resolved in order to provide a solution that satisfies all the parties involved. The design of the cable stayed structure presented a number of configuration challenged, most specifically the fact that while the agreed location of the new bridge was on a skewed alignment the navigational requirement stated that the pier substructure should be parallel to the river flow. The width of the navigation channel meant that a dual dual tower structure was out of the question. One of the most demanding constraints was the requirement of the U.S. Coast Guard that any substructure units falling within the 100-year flood elevation must be positioned such that their faces are parallel to the flow of the river. The alignment that had already been chosen and approved forms a 70 degree skew. As a solution, substructure units were reconfigured with tapered pier caps having an elliptical cross section that would be perpendicular to the bridge center line. After having overcome the numerous constraints, the bids for construction are due to be invited in November this year.
