Restoration of the Vasco da Gama cable-stayed bridge, Lisbon

Feb 08, 2023
The Vasco da Gama Bridge is a cable-stayed bridge over the Tagus River connecting the municipality of Alcochete with Lisbon, Portugal. At over 17.3 km, it is the second longest bridge in the European Union.

The project in which ULMA has participated consisted of creating access systems to the stay cables at the top of the pillar and access to the bottom of the board to allow the replacement of certain stay cables damaged by a traffic accident. It was also responsible for staff training, inspections, assembly and disassembly of the scaffolding. The Bridge concessionaire is Lusoponte and it’s been carried out by Freyssinet.

The erection process of ULMA modular scaffolding started from the upper part of the pylon, at a height of 150 m, and from there it descended approximately 20 m to the last stay cable.

As this was a top-down assembly at a considerable height, the safety of all involved and of third parties was vital, as the traffic on the bridge was still in operation. This situation was always present in the project development to guarantee safety and the correct functioning and application of the scaffolding for the planned works.

You have all the details of the project and the client's testimonial in this video.

The images are impressive!
