Tower Road rolling lift bridge carries the busy A554, linking Birkenhead with Wallasey on the Wirral. It forms the main route into the docks and the nearby ferry terminal. The new bridge replaced an ageing Scherzer rolling bridge built in 1933. The 33.7m moving span is lifted by two hydraulic cylinders which are assisted by a 482 tonne counterweight system. It was opened in 2018.
