The San Benito Viaduct is a railway bridge over the Lérez River. It is in the Pontevedra – Cerponzons Section in the High Speed Atlantic Corridor, located near the city of Pontevedra, in the Northwest of Spain. The bridge is 171 m long and it consists of 3 spans: 57 m + 84 m + 30 m. It is a hyperstatic post-tensioned concrete structure: The superstructure is a variable depth single cell box girder, with a total width of 14,0 m. First, the side spans were built by means of a full shoring. After that, the central span, over the Lérez River, was erected using a segmental cantilever construction method, with cast in place segments, by means of a form traveller. Due to the presence of a tunnel following the viaduct, the last span is only 30 m long. Because of that the bearings in the abutment 2 were properly anchored to avoid uplift.
