The construction of the Arrabida Bridge was one of the works in which Eng. Araujo Sobreira was involved more specifically in the design and construction of Centering.
This remarkable engineering work, proposed by Eng. Edgar Cardoso, had such a complex involving a remarkable set of Technicians, not only in the bridge construction itself but also, as in this case the construction of the centering.
At the end of the project Eng. João Sobreira was then asked to write a short text describing the process used to assemble the truss, this document is presented here in conjunction with the drawings that where then produced.
