The main dock at Sharpness
Sharpness is a port town on the River Severn in Gloucestershire. This is one of the most inland ports in Britain but the eighth largest in the South West. It stands on the River Severn at a point where the tidal range, though less than at Avonmouth downstream is still large; 33 feet at a typical spring tide).
Sharpness docks began as a basin giving access to the Gloucester and Sharpness Canal. There were no port facilities at Sharpness itself and all traffic proceeded up the canal to Gloucester. The original Old Dock opened, with the canal, in 1827. The dock was separated from the Severn by a lock gate. The level of the basin varied for the hour or two for which the gate was open and so it was isolated from the canal by a lock with two gates. This lock was improved over time, expanding to be a ship lock 163 feet in length and 38 feet broad and a smaller lock for Severn trows of 81 feet and 19 feet. An intermediate lock gate was also provided in the larger lock, allowing shorter vessels to pass through more quickly and with less water consumption. A house for the Harbour Master was provided on the seaward dockside alongside the river gate. Today the Severn Area Rescue Association maintain a rescue station in the old house.
The size of the Old Dock became a drawback for increasingly large ships and so in 1874 a floating New Dock was opened to the South. This had several advantages over the Old Dock: its entrance was now through a tidal basin and a large lock. This gave a constant water level within the dock, matching that of the canal, and so no locks were needed between dock and canal, encouraging traffic. The lock was 320ft long and 57ft wide. For ships longer than this, the basin itself could also be used as a lock. A graving dock was provided parallel to the lock. This constant level encouraged the building of wharves and warehouses. With the new rail connections available to Bristol, Sharpness also developed as a port in its own right. At first the only stone quay was on the landward side of the dock, but after a railway swing bridge was built across the dock, the island area between the two docks also developed as a quayside.
In typical fashion for the competing pre-Grouping railway companies, there were not only two railway lines into Sharpness, but there were even two separate bridges across the dock: the Midland Railway's low level bridge from the southeast to Berkeley, and the Great Western's high level bridge from the north and across the Severn. The line to the south was the Sharpness branch of the Bristol and Gloucester Railway, by this time part of the Midland, and opened on 2 August 1875. Although this line left Sharpness to the south, it joined the main line facing north. The northerly route across the bridge opened on 17 October 1879. An important development was on 19 March 1908 when a short Great Western line to the south of the previous junction formed the Berkeley triangle, giving a direct route to the Great Western main lines, and thus Bristol, through the Westerleigh Loop. and the opportunity it gave the Great Western for a route between Bristol and Birmingham, would be a cause of legal contention between the GWR and the Midland for some years.
After the New Dock was opened, the Old Dock and its cumbersome lock access to the canal was used less and less. From 1908 the old entrance was abandoned and the Old Dock became used for ship repair. After age, storm and tide damage led to the gates being removed and sealed permanently in the 1990s, the dock water level was raised to that of the canal and the locks could also be abandoned.
Just north of Sharpness the river and canal were crossed by the Severn Railway Bridge, until it was damaged beyond repair by a barge collision in 1960. The bridge was locally convenient, schoolchildren crossing the river to go to school, but it was soon superseded by the double-tracked Severn Tunnel on the faster and more direct route between Bristol and Newport.
Proposals to reinstate a river-crossing at this point are frequently made especially by the local authorities in Lydney, which lies almost opposite Sharpness.
The Port Authority for the impounded dock is British Waterways, but the quayside activities are run by Sharpness Dock Limited. The competent harbour authority for the river from the Severn Road Bridges up to Sharpness is Gloucester Harbour Trustees - they are responsible for navigation aids in the channel and for the provision of pilots. Pilotage up the river is compulsory (except for exemption holders) for all vessels over 100 deadweight tons.
Between 1939 and 1966, the demasted sailing ship Vindicatrix was moored in the Old Dock as a training hulk for the Merchant Navy.
