The Blackwall Rock was a reef in the River Thames near Blackwall in East London at short distance upstream from Blackwall Stairs and between the entrances of the West and East India Docks. The rock provided a useful shelter for moored vessels, but also proved a hazardous obstruction to river navigation as it was sometimes less than 3 feet (1 m) below the surface at low tide.
The entrance to the West India Docks, just to the south-west of the rock, was substantially obstructed by the reef upon the docks' opening in 1802. In 1803, Robert Edington surveyed the rock estimated its dimensions as 600 by 150 feet (183 m × 46 m). An 1846 report by the Tidal Harbours Commission described it as an outcrop of plum-pudding stone.
Early attempts to break the rock with explosives were largely unsuccessful. William Jessop was engaged by Trinity House to undertake the rock's removal which he did using a chisel, operated from a barge much as with pile driving. This method successfully reduced the height of the rock by 15 feet (4.6 m), after which a cylindrical coffer dam was employed to allow workers' access to remove rubble.
Through his leadership of the MR, SER and MS&LR, Watkin had the amibtion to construct a new mainline railway connecting the north of England, via London and Kent to the continent. Although his plans for a channel tunnel to be constructed by his Anglo-French Submarine Railway were never realised, the MS&LR constructed its London extension in the 1890s from Annesley, Nottinghamshire to the MR's station at Quainton Road in Buckinghamshire to a continental loading gauge. Reflecting its enhanced connections the MS&LR changed its name to the Great Central Railway in 1987.
To encourage tourist day-trips on the MR, Watkin planned a pleasure grounds at Wembley Park, with a large tower, "Watkin's Tower", intended to be larger than the Eiffel Tower. The park opened in 1896, but because of cost and structural problems, the tower was never completed and was demolished after Watkin's death. The site was subsequently used for Wembley Stadium.

Continuation of the West Cross Route northwards under the roundabout was cancelled leaving two short unused stubs for the slip roads that would have been provided for traffic joining or leaving the northern section.
