| Abstract: |
The viaduct over Rego das Lamas is part of the Lalín (Baxán) – Lalín (Anzo) section of the High Velocity Railway between Orense and Santiago, which remains under the jurisdiction of ADIF. The viaduct is designed as a 245 meter, composite concrete-steel structure that allows crossing of the railway tracks over the AP-53 motorway by 80 m bowstring span: two arches along with steel ties. Nine hangers made of Y1860S steel and formed with 150mm² strands connect every arch with its tie. The bowstring span has been erected over the highway by incremental launching from the construction yard into its final position over the piers 3 and 4. |
