Headland Archaeology (UK) Ltd undertook a programme of Archaeological Trial Trenching on behalf of Amey PLC as part of pre-determination works at West Waterloo Docks in Liverpool. The work was carried out prior to the commencement of the Mersey Waters Proposed Northern Link Road which will provide a link to the proposed Isle of Man ferry terminal on West Waterloo Dock. The trial trenching consisted of the excavation of three trenches located along the dock, in order to establish the presence or absence of the 19th century dock wall. Trial trenching revealed the presence of the dock wall in Trench 2 along with associated sandstone sett and bituminous floor surfaces and a red brick wall. The dock wall was absent in Trenches 1 and 3 both of which featured historic floor surfaces, sequences of made ground deposits and some small remnants of structures. Trench 1 also revealed a large cast concrete structure probably associated with the sewerage system. The excavation revealed evidence for the dock wall as well as associated dock structures, the form and function of which is unknown and would require further investigation in order to provide clarification. It is certain that the proposed works, as they currently stand, would impact on the heritage assets.
