Rande Bridge Expansion. Erection Process of the New Deck.

Abstract

The Rande Bridge is an essential crossing point in the area of the Vigo Estuary. During the expansion
works carried out it was essential that all the needed works did not affect neither the passing traffic nor
the marine environment of the Rande Strait. For this reason, the construction method selected for the
erection of the new deck was double aimed to minimizing traffic restrictions, always maintaining at least
one lane open in each direction, and to not affecting the surrounding environment. These objectives were
also conditioned by the limitations imposed by the existing bridge. This paper presents the details of the
erection method selected to meet both these requirements and a proper schedule.
