Planned dock facilities included a north quay, rail fed coaling jetties on the east quay, and outfitting jetties and slipways on the south-east side. A third lock wide was to be constructed adjacent east and parallel with the existing locks of the fish dock; additionally the fish dock east entrance pier was to be removed, and a new pier constructed on the east side of the new lock. Other changes required included the rerouting of a sewer and its outfall channel further east. The estimated cost of the works was £1.418 million of which the Corporation was enabled to raise £1.25 million, the remainder by the LNER, who agreed to a thirty-year lease on the dock. The company of Sir Lindsay Parkinson was contracted to carry out the work. A.E. Tarrant was the resident engineer.
