Abstract: |
The New Boca del Cerro Bridge is situated in southern Mexico (city council of Tenosique, Tabasco) and is the most emblematic structure of Section 1 of the new “Tren Maya” railway. Located in a Protected Area and a strategic crossing pint where exists an Arch Bridge built in 1950, the new bridge was designed to be as invisible as possible with the aim of generating minimal intrusion nor competition with the existing bridge, thus maintaining and enhancing the beauty of the enclave. The structural solution selected to effectively achieve all these design factors was a variable depth composite truss spanning the entire river course by means of embedment in two lateral concrete compensation spans, resulting a span distribution of 30+160+30 m. The selection of the structural typology was also strongly conditioned by the advantages of the construction process considered: incremental cantilevered erection of the main span from both side spans, independently of the river. |
