Struck by barges The strengthening work had been completed on 18 spans and work was proceeding on the remainder when the bridge was struck and badly damaged, 30 minutes after the passage of the last passenger train on 25 October 1960. Two barges in the River Severn were out of control in thick fog and struck pier 17, bringing down the pier and the two spans it supported. The vessels were the
Wastdale H and the
Arkendale H. The displaced spans fell on to the barges and ignited their petrol and oil cargo. In the conflagration, five crew members of the barges died. Still out of control the barges continued upstream on the flood tide and grounded on sandbanks, still carrying 70 yards or so of fallen railway track on their decks. The Chief Civil Engineer of British Railways, Western Region, gave an account of the course of events, summarised from a Board of Admiralty inquiry. A fleet of 26 barges was brought up from Avonmouth: There seems to have been some confusion about how to disengage them from one another and:
Stabilising the bridge Two spans collapsed. On the morning following the fall, the first Lydney to Sharpness passenger train ran via Gloucester, but the service was then suspended. On 27 October 1960 a passenger service between Berkeley Road and Sharpness was instituted. This continued until 7 September 1964, when the branch was closed to passenger traffic. A pier adjacent to the fallen pier needed to be stabilised, and this was done by driving a timber pier to support it. During the course of this work, the barge carrying the contractor's piling rig broke away at night when it was anchored unmanned. Again in flood tide conditions to travelled upstream. The Resident Engineer commandeered a power launch and tried to board the barge and take control, but his propellers were fouled by trailing ropes and he was unable to do so. The barge then drifted downstream on the subsequent ebb tide, and the crane jib struck the bridge, causing the collapse of the crane jib. Shortly after this another barge engaged in the work was carried upstream and struck one of the other piers, demolishing the
fenders but causing little damage to the piers themselves. Passing the bridge upstream, it later moved downstream again and struck one of the columns, removing about 8 square feet of the cast-iron caisson. The barge capsized three or four miles downstream with total loss of life.
Insurance The question of insurance arose; at the time the matter was governed by marine insurance law, which limited the compensation according to the weight of the vessel doing the damage. British Railways received less than £5,000 in compensation. The
gas board also had a 12-inch gas main fixed to the bridge; they had to lay a new one of about 15 miles in extent, and they received less compensation than British Railways. The contractor who lost compressors and plant to a value in excess of £10,000 received less than £100 in compensation.
Further damage to the bridge On 17 February 1961 the tanker
BP Explorer capsized on approaching Sharpness. Out of control, it drifted upstream with the tide, passing the bridge; it struck pier 20 on travelling downstream again on the ebb tide. Its entire crew was lost, and damage to the extent of £12,740 was caused to the bridge. Two floating cranes had been brought in to assist with the repair work to the bridge; they were the
Tweedledum and
Tweedledee. On 14 April 1961 they broke away from their moorings on the flood tide and passed above the bridge, then striking the
dolphins of pier 20 on the way down on the following ebb tide. The jib of one of the cranes struck the superstructure of the bridge.
Closure of the Berkeley Road Loop The Berkeley Road Loop had been built by the Great Western Railway when the Badminton line was opened. It had been used by South Wales-to-Bristol trains at weekends when the Severn Tunnel was closed for repairs. Any residual goods train access to Sharpness could be accommodated via Gloucester, and as staffing of two signalboxes was necessary to use the loop, it was decided to close it. The closure took place in 1963.
Demolition Some considerable time was spent in deciding on the future of the bridge, and a contract was let to commence restoration. However eventually it was decided to demolish the bridge instead. When 24 contractors' firms were invited to quote for the work, 21 of them declined to accept the work. Of the three who quoted, one contractor quoted about £750,000 and another over £200,000. A third quoted about £75,000. This cheapest quotation was accepted, and the firm used a Magnus II salvage crane on hire from Ulrich Harms of Hamburg. Nineteen spans were successfully dismantled, but there remained two larger spans of 108 feet. These were beyond the capacity of the crane, and they were cut so as to fracture when pulled off the supporting piers. Unfortunately when this was done they fell but did not fracture. Only about a quarter of the ironwork of these spans was recovered. After the completion of removal of the superstructure there remained the problem of removing the concrete-filled columns down to 20 feet below water level in the area of navigation. Demolition of the masonry approach viaduct too became much delayed; it was eventually dropped by explosives on 10 March 1968. It was at this stage that the contractor got into financial difficulties and on 20 November 1968 went into liquidation. British Railways continued the work by direct labour, using the firm of Swinnerton and Miller for explosive demolition.
Further shipping disaster In 1969 a small former car ferry, the
Severn King, was employed in assisting with the demolition work and on 4 July she broke adrift and became impaled on the stump of pier no. 2. It was necessary to wait for a spring tide high enough to refloat her, and this was done on 28 July; the
Severn King was beached at Sharpness and cut up there.
Swing bridge demolition The final stage of removal of the bridge structure was the demolition of the Sharpness swing bridge, and this was completed on 13 May 1970. ==Current use==
