Liu To Bridge
Liu To Bridge is a bridge over the valley of Liu To, Tsing Yi Island, Hong Kong. It is part of Tsing Yi Road West. The structure is numbered N547 by Hong Kong Government.
Built between 1985 and 1987, it spans and is a 3-span bridge with dual 2-lane roads. As Liu To is a steep-side valley, in order to avoid temporary work on the valley floor, twin prestressed concrete boxes were stacked incrementally during the construction to provide a short section across the valley.
