Abstrait:

The construction of a ring road allowing traffic decongestion in the city of La Paz, Bolivia is currently being finished. The new road should save three parallel valleys with bridges. These three consecutive bridges have similar characteristics and therefore they are called Trillizos (the Triplets). They all are three-span extradosed concrete structures, with maximum span of 113,5m. They are built through balanced cantilever method. The aesthetic, functional, environmental and construction aspects condition and define them. This paper describes the bridges, the design criteria and the construction process.
