ABSTRACT
ABSTRACT: Two types of bridges with progressively erected decks are described in terms of the architectural and structural solution and technology of their erection. The first type is formed by a concrete spine box girder that is additionally widened by precast struts and cast-in-place overhangs. The bridges have spans from 42 to 69 m; their width is from 25 to 31 m. The second type is formed by a steel trough that is composite with a concrete deck slab supported by steel struts. The deck slab is cast in a formwork formed by precast members. The bridges have spans from 45 to 66 m; their width is from 25 m.
