Design and construction of the substructure and prestressed concrete
superstructure for Bridge 7 on the Bogota-Villavicencio Highway. The bridge has
two structures: one constructed using a post-tensioned cast-in-place segmental
balanced-cantilever method. This structure is supported by caissons 55 M deep
and piers 64 M high. The other structure was constructed using a post-tensioned
cast-in place span-by-span method.
