Possibly the last of Castlefield's great warehouses was the Great Northern Warehouse of 1896 to 1898. This was a trans-shipment warehouse that had railway access on two of its floors, road access and canal arms from the Manchester and Salford Junction canal in the basement. This was one of Britain's first large steel-framed buildings (81m x 66m). There were hydraulic lifts capable of raising fully laden railway waggons between the floors. To service the building the Great Northern Viaduct was built parallel to the Cornbrook Viaduct over the basin, and over the Kenworthy Warehouse. The country's longest Victorian commercial terrace was built to mask it from Deansgate.
