Fourth Bridge prepares for new construction phase with first crossbeam installation

The Fourth Bridge over the Panama Canal is approaching a new construction phase with the installation of the first crossbeam on its eastern main tower, known as M3.

The tower, being built in the Arenera sector of La Boca in Ancón, currently stands 53 meters high. It is designed to reach 186 meters, roughly the height of a 62-story building. Along with the western tower, M4, it will support the bridge’s cable-stayed section.

Manuel Alvarado, the project director, said the crossbeam installation will allow crews to continue raising the columns by another 50 to 60 meters. A second crossbeam is planned later, and the cables supporting the main bridge deck will extend from it.

Alvarado said the deck could be installed in 2027. Its fabrication is scheduled for the end of this year through industrial processes carried out away from the construction site.

The cable-stayed section will span 965 meters. Its central span over the Canal’s navigable channel will measure 485 meters, while the two side spans will each measure 240 meters. Two transition piers and the two H-shaped towers will provide the main structural support, with 152 cables holding the deck.
