50년전 영국 포스로드교 건설 광경 Forth Road Bridge, incredible archive photos emerge of how their predecessors built it 50 years ago(VIDEO)
Don't look down! As engineers battle to re-open the troubled Forth Road Bridge, incredible archive photos emerge of how their predecessors built it 50 years ago
- The stomach-churning images show workers helping to fix the steel suspension cables into position 500ft in the air
- The photos were taken for engineering firm Sir William Arrol & Co which produced and installed the steelwork
- When it opened it was the first of its kind in the UK, the longest outside the USA and the fourth longest in the world
- Route between Edinburgh and Fife was closed this month after a crack was discovered under the carriageway
- 일반사람이 보면 심장이 두근거리는 이 아찔한 사진은 영국(스코틀랜드)의 50년전의 포스로드교 건설 광경이다.

Incredible archive photos of how the Forth Road Bridge was built 50 years have emerged, just weeks after it was closed for major repair works.
The stomach-churning images show workers helping to fix the steel suspension cables into position 500ft above the Firth of Forth in Scotland.
The photos were taken for engineering firm Sir William Arrol & Co which produced and installed the steelwork for the bridge. They were retained by a member of staff who cleared out the officers when the firm went bust in the 1980s.
In September 1958 the Forth Road Bridge Joint Board oversaw construction on the site, while Freeman Fox & Partners, Messrs Mott and Hay & Anderson looked after the design

The major connection between Edinburgh and Fife was closed this month after a crack was discovered in a truss under the carriageway.
It was revealed today that engineers are working towards a deadline of January 4, to have the A90 route back up and running.
A spokeswoman for the bridge operators Amey said engineers were 'working towards' having the bridge within that timescale, but noted that this was 'dependent on weather conditions'.
Scottish Transport Minister Derek Mackay has agreed to release all the information regarding the maintenance of the bridge after opposition leaders demanded 'full transparency' about when the Scottish Government became away of the urgent issues.
The need for a road bridge over the Firth of Forth came to light in the 1920s with the rising popularity of the private car
Proposals were made in 1923 and the dbridge was backed by the Ministry of Transport in 1924. Sites were identified but progress was halted until 1947 due to the Great Depression and World War II

In September 1958 the Forth Road Bridge Joint Board oversaw construction on the site, while Freeman Fox & Partners, Messrs Mott and Hay & Anderson looked after the design.
Britain's three largest engineering firms at the time, Sir William Arrol & Company, The Cleveland Bridge & Engineering Company and Dorman Long (Bridge & Engineering) Ltd joined forces to create a consortium called ACD Bridge Company Ltd.

The main cable anchorages, planted into the ground on both shores, as well as the two main towers were completed in 1961
A special school in South Queensferry was needed as spinning several wires of the main cables back and forth across a river was unheard of in Europe at the time

The main cable anchorages, planted into the ground on both shores, as well as the two main towers were completed in 1961. A special school in South Queensferry was needed as spinning several wires of the main cables back and forth across a river was unheard of in Europe at the time.
By August 1962, 30,000 miles of steel wires had been spun together to make up the main cables. Nearly 40,000 tonnes of steel and 125,000 cubic metres of concrete went into the bridge's overall construction.
The Union Flag and Lion Rampant marked the occasion of the final box girders completing the main span in 1963, with the roadway and footpaths finishing a year later.

The final bill for construction amounted to £19.5 million, and the bridge was opened by Her Majesty The Queen on September 4, 1964. Its motto was 'Guid Passage', Scots for 'good passage'
At this time, it was the first bridge of its kind in the UK, the longest outside the USA, and the fourth longest in the world

At this time, it was the first bridge of its kind in the UK, the longest outside the USA, and the fourth longest in the world.
The bridge's two main towers and cross-bracing were strengthened to accommodate the increased weight of traffic in 1990, the main tower legs were strengthened in 1998, and the 768 hanger ropes from which the suspended decks hang were replaced between 1998 and 2000.
A new bridge called the Queensferry Crossing is being built and is due to open next year.
OPPOSITION PARTY CALLS ON SCOTTISH GOVERNMENT TO RELEASE EVERY DOCUMENT ON BRIDGE MAINTENANCE
Labour has called for every document relating to the maintenance of the Forth Road Bridge to be made public.
The call was made after it was revealed that some heavy loads were banned from crossing it in February.
A confidential email released by the party shows that chief engineer Barry Colford ordered restrictions on the passage of vehicles weighing more than 150 tonnes after analysis of the loading on the bridge's truss end links - one of which has since cracked, forcing its closure.
'The restriction needs to be in place until all the truss end links are either strengthened or replaced,' he said in the document sent to Lesley Hinds, convenor of Edinburgh City Council's transport, infrastructure and environment committee.
Scottish Labour deputy leader Alex Rowley said the email undermined claims by SNP ministers that the crack was 'unforeseen and unforeseeable'.
Transport Scotland insisted the restriction was not related to the current problem, which it said was 'unexpected and not predicted'.
Mr Rowley said: 'The fact that as far back as February there were concerns about the safety of the bridge is very concerning.
'We now know the chief engineer was so concerned about the safety of the bridge that certain vehicles were prevented from travelling on it.
'We need full transparency from the SNP Government about this. The idea that problems with the bridge were unforeseen, as Nicola Sturgeon and Derek Mackay have claimed, just doesn't stand up to any scrutiny.'

Opposition parties have called for a full parliamentary inquiry into the closure of the vital crossing, which is due to reopen in the new year.
Mr Rowley added: 'We know the SNP Transport Minister misled Parliament when he claimed there was no link between cancelled repair works in 2010 and the damaged area now.
'And we know the SNP Government's budget cuts resulted in vital repair works being put off.
'The thousands of people and businesses affected by the closure of the Forth Road Bridge deserve full transparency.'
Scottish Liberal Democrat leader Willie Rennie called for any parliamentary inquiry to take evidence from Mr Colford as well as former operating officer Alistair Andrew.
A Transport Scotland spokesman said: 'The restriction on exceptionally large abnormal loads was not related to the present defect on the bridge. It was related to potential unacceptable overstress to the truss end brackets and associated welds within the towers. This is being addressed by the ongoing strengthening works.
'Restrictions on loads of this type have little impact as there are very few movements of this size and they are agreed in conjunction with Transport Scotland, local authorities and Police Scotland who escort such loads.
'The defect which has resulted in the closure of the Forth Road Bridge was identified in the last few weeks. It was unexpected and not predicted by previous truss end link analysis.
'The work that was being considered in 2010 was prompted by concern about another part of the truss end link system affecting the towers and not the part that fractured.'
The bridge's two main towers and cross-bracing were strengthened to accommodate the increased weight of traffic in 1990, the main tower legs were strengthened in 1998, and the 768 hanger ropes from which the suspended decks hang were replaced between 1998 and 2000
