Description

The Contreras Viaduct is a twin-deck superstructure with variable depth trusses and double composite action above the piers.

Both halves of the steel superstructure were launched from the abutments. After  launching these semi-girders, they were connected together at mid-span and the top slab was cast.

This main span is completed with a statically determined approach span which is also a composite truss.
