Sheffield City Council’s Design and Property (Structures Division)  used LUSAS Bridge to undertake an assessment (strength) check of High Bridge, a 13th century quadripartite arch bridge on behalf of Lincolnshire County Council, the bridge.s owner. High Bridge, which carries Lincoln’s main pedestrian thoroughfare, had been structurally assessed twice before with conflicting outcomes. The LUSAS analysis provided an independent third assessment and proved the structure was safe for the imposed loading.
