Tony Gee was appointed to undertake the detailed design for the reconstruction of the aqueduct using fibre reinforced polymer (FRP) materials, which was a first for Network Rail.
Our innovative design adopted FRP materials for Overbridge 47, in conjunction with development of the trough profile and the independent liner, to provide a durable and low maintenance replacement for the aqueduct. The designed solution and methods also mitigated the impact of the works upon the cutting, which was imperative due to location within a designated Site of Special Scientific Interest.
The new aqueduct comprises an open trough, similar to the previous structure, but with greater depth and cross-section profile to improve the flow capacity.
