/ ABSTRACT
The work carried out on theSanta Marta Bridge, located at KP 6+450 of the PO-300 road (T.M. Vilanova deArousa – Ribadumia, Pontevedra) over the Umia River, is detailed. The former bridge crossed the river with an intermediate metal arch with a lower footbridge hanging from it. On April 18, 2023, it was closed to traffic when several ofits suspension profiles broke. After studying the structure, it was concluded that the most appropriate thing to do was to dismantle it and then build a newbridge. To replace it, a Warren-type truss with an isostatic span of 54 metreswas designed. The lower chord is used for pedestrian traffic.
