To link the mainland with an inaccessible island site of the 13th-century Tintagel castle in Cornwall, England, engineers are cantilevering both halves of a 68.5-meter-long pedestrian bridge in small pieces and without heavy equipment.
With only footpaths for access, “design was driven by buildability,” says Matthieu Mallié, a partner of Belgium-based structural engineer Ney & Partners. Working with William Matthews Associates Architectural Practice, the team in 2016 won an international design competition for the crossing run by site owner English Heritage.
