The New Boca del Cerro bridge, on the Maya Train, Mexico

We want to share a video courtesy of Recal of the progress of the execution of the New Boca del Cerro Bridge over the Usumacinta River, in section 1 Palenque-Escárcega of the Mayan Train, in Mexico.

In the next followings weeks the work is going to be very intense. We will keep you up to date with the news, especially the progress in the cantilever assembly of the truss from both abutments.

The new viaduct is located parallel to and very close to the impressive Boca del Cerro arch bridge, in service since 1950.

The typological and structural solution chosen for the new Mayan Train bridge was based on the condition of seeking the greatest possible transparency, resolving the central span of 160 m by means of a steel truss with double composite (steel&concrete) action, which allows jumping the great span of the river Usumacinta -the largest in Mexico-, respecting its integration into a natural environment of extraordinary beauty and avoiding “competing” with the existing bridge, which must continue to maintain its preponderance in the landscape.

The large central span is embedded at the ends by means of two short hidden spans, 30 m long, with a post-tensioned concrete box girder cross section, anchored in abutments, and will be executed by cantilevered advance using a mobile gantry that avoids any dependence on the riverbed.

Once completed, the bridge will become the largest span of all of the Maya train.

IDEAM | A TYLin Company is collaborating with Mota-Engil México, and has carried out the conception, the detailed design and is providing technical assistance during execution. Recal  is the Mexican steel workshop that is executing the steel structure.
