In 1868, Waterloo Dock was split in two separate basins; East Waterloo Dock and West Waterloo Dock.[4]
Initially planned eleven years earlier, the lock entrance from the Mersey was finally opened in 1949. Construction was delayed due to the Second World War.[4]
The dock closed to shipping in 1988. The entrance channel from the river and part of the dock has since been filled.
In 2007, work began on a £20 million extension of the Leeds and Liverpool Canal, providing a further 1.4 mi (2.3 km) of navigable waterway and encompassing Princes Half Tide Dock.[5]
A new 6.5 m (21 ft)-wide channel from Trafalgar Dock to the northern end of West Waterloo Dock will be excavated as part of the canal route.[6]
The extensive Waterloo Warehouse has since been converted into residential apartments.
