The Tenth Street viaduct project in Lincoln, Nebraska, showcases two unique bridge structures. The first is a pedestrian/bicycle overpass which features spliced, prestressed concrete /-girders, designed and built using a new continuity technique. This structure incorporates level landings for the disabled and a deck heating system. The second structure is a vehicular viaduct. Design of this structure included alternative superstructures - a continuous, composite steel plate girder, and a composite, spliced concrete prestressed girder system made continuous via full-length post-tensioning. This paper presents the various project phases, with an emphasis on the pedestrian/bicycle overpass and the implementation of the new girder continuity technology.
