Proposal to replace the existing viaduct over the East West railway line in the UK. The objective is to replace a viaduct that is 60 years old with a total of 30 spans and approximately 600 m in length that crosses over the track bed. The proposal consists of using a prefabricated modular solution, consisting of a "U" section, that allows maintaining or even improving the existing clearance, that can be adapted to different spans and types of piers, and that allows integrating the structure with the platforms of the future station expansion.
