Abstract:
The Owensboro Bridge will carry four traffic lanes across the Ohio River. The 1200-ft main span and two flanking spans are supported by stay cables. Design considered constructibility, inspection, maintenance, and durability. Steel cable connection frames are housed in large chambers in the towers for easy access. The cable lower end is anchored to a connection plate that is directly bolted to the web of the edge girder with no eccentricity. Between approach spans and back spans, a special moment connection is designed for continuity. Concrete counterweights instead of tie downs are used at anchor piers.
