The River Don Viaduct will cross the Sheffield & South Yorkshire Navigation at Mexborough where it is still used as a commercial navigation, as well as increasingly for recreational boating.
The viaduct piers should span the full width of the canal and its towpath and provide the necessary headroom specified by the Canal & River Trust. The viaduct will be a major landmark structure and its design should seek to seamlessly integrate with and enhance the location.
HS2 Phase 2B affects 16 inland waterways, both canals and river navigations, in at least 22 locations, including three canal restoration schemes.
