Design and Construction of the Cincinnati/Northern Kentucky Airport Taxiway ‘N’ Bridge

This paper presents the design and construction of a unique bridge built as part of the Cincinnati/Northern Kentucky International Airport. The bridge is called Taxiway ‘N’ Bridge. Severe depth limitations, heavy aircraft loading and short construction duration required a creative solution. The bridge is about 217ft wide, and had to be built in three stages of 72ft width. The span is 87ft long. The superstructure system selected for the bridge was a 4’-6” deep cast-in-place voided slab two-way post tensioned system. Void sizes and locations were optimized for structural efficiency. Design consideration including transverse and longitudinal load distribution of aircraft loading will be presented. Also, new provisions for durable post-tensioning will be discussed. The substructure was also optimized through the use of stub abutments and mechanically stabilized earth. The MSE walls had to be designed for the equivalent to aircraft loading. Construction of the bridge will be illustrated, including false-work considerations. Finally, the cost effectiveness of this structural system will be discussed.
