Merthyr’s Bridges: St Tydfil’s Bridge

Not exactly history, but St Tydfil’s Bridge is an iconic structure that will be part of Merthyr’s History in future generations. We all know it, you either love or hate it, but what do you know about it?

Here’s a transcription of an article that tells us all about its construction:

An iconic steel composite bridge forms the centrepiece of a multi-million pound regeneration scheme in the South Wales town of Merthyr Tydfil.

Spanning the River Taff and connecting a recently redeveloped college with the town centre, the River Taff Central Link Bridge forms an important element of Merthyr Tydfil’s £24M regeneration programme.

The new bridge will offer better transportation links across the River Taff

Funded by the European Regional Development Fund and Welsh Government, the regeneration masterplan encompasses a number of town centre enhancements with the new road bridge helping to make the riverside area an attractive destination for future investment.

The council’s Regeneration Manager Gavin Lewis wanted something that would be a feature and not simply a typical highway bridge structure. A number of design options went out to consultation with the local planning and highways authorities, together with other stakeholders, and the favoured design was for a bridge with an iconic arch.

Once a bridge design was selected locally based civil engineering company Alun Griffiths was chosen as the principal contractor for the project, while Mabey Bridge was awarded the bridge construction subcontract package.

Designed by Capita, the bridge’s stand out feature is 136t skewed arch. Measuring 40.9m across its base and reaching a maximum height of 18.5m, it was fabricated from 60mm thick plate. Connecting the arch to the bridge deck are a total of 14 × 80mm diameter hangers ranging in length from 4.7m to 22.5m.

One of the project’s main technical challenges revolved around the hangers and the associated cable tensioning. “During the non-linear analysis of the installation and stressing procedure for the hangers, we found that some hangers would go into compression if the full pre-stress design was induced in an adjacent hanger,” says Christopher Prosser, Capita Project Engineer. “We therefore had to design an incremental tensioning sequence to prevent this occurring. The designed sequence was later streamlined by Mabey Bridge during the construction phase in order to speed up the process.”

The appearance of the bridge was critical to the overall design and so it was decided that each hanger fin plate would be designed with the same geometry, but with varying orientation to suit the alignment of the hangers. This required Capita to extensively model each element to ensure there were no clashes and determine the practicalities of completing the internal welds, while ensuring the alignment of the hangers between the top and bottom plates was correct both aesthetically and structurally.

When designing the structure it was also necessary to take into account the BS EN 1993-1-11 requirement for the loss of a hanger without any restriction to live load capacity. “This required us to model what effect the loss of a hanger had on the remaining structural elements for the critical loading case. This analysis resulted in the increasing of the diameter of the hangers and associated fixings,” says Mr. Prosser.

For the site erection programme, the 29m long x 19.8m wide deck was the first steelwork to be installed earlier this year by Mabey Bridge. It is formed with a ladder configuration with two main 900mm deep × 600m wide outer girders, each 29m-long, connected by a series of nine crossbeams.

“We erected the deck steelwork using MEWPs positioned on each riverbank in conjunction with one 250t capacity crane,” says Andy Hosking, Mabey Bridge Project Manager. “Once the beams were erected we then bolted on the cantilevers which support the parapets as well as having the deck connection for the hangers.”

Mabey Bridge’s contract required it to have input in a number of aspects relating to the project, not just the steelwork detailing, but also construction methodology, and cable installation and stressing. However, the company’s main recommendation was to fully assemble the arch and then lift the complete structure into position.

The arch was lifted into place as one large piecewidth

This eliminated working at height as well as having environmental benefits as no trestles were installed into the fast flowing river. Working in this way also reduced the construction programme as steelwork fabrication was carried out off site by Mabey Bridge while Alun Griffiths was constructing the substructure on site.

The arch was transported to site in four equal sections from Mabey Bridge’s Newhouse manufacturing facility which is 88km away from Merthyr Tydfil. Once on site, the sections were placed on temporary trestles and welded together to produce the continuous and completed arch.

Using a single 550t capacity mobile crane positioned on one of the riverbanks, the entire arch was lifted into a vertical position, slewed over the river to its final position where it was fixed to the abutments. “The entire lifting procedure took eight hours and a large crowd, including school children and council representatives, gathered to watch,” says Mr Hosking.

Commenting on the bridge, which is scheduled to open in November, Daniel Francis, Project Manager for Merthyr Tydfil County Borough Council, says: “It is an iconic structure that also opens up areas of the town for future development. It is also a key structure in our redevelopment programme that will, along with a new road system, cater for our anticipated increase in visitors to the town.”

Watkin George

Today marks the 200th anniversary of the death of one Merthyr’s greatest pioneers – Watkin George.

Watkin George is not a name that most people think of when talking about Merthyr’s great men of the past, but his contribution to the town’s history and his legacy is incalculable.

Born in about 1759 in Trevethin, Pontypool, very little is known about his early life, other than he trained as a carpenter, but by his early thirties, he had had married Anne Jenkins (of also of Trevethin), and had moved to Merthyr to work at the Cyfarthfa Ironworks as an engineer, as his expertise in designing and building metal structures had become well known.

He soon became the foundry manager at the Cyfarthfa Works, and in 1792, Richard Crawshay appointed him as a partner in the business. One of his first projects as partner was designing the Pont-y-Cafnau (Bridge of Troughs), a combined tramroad and enclosed aqueduct built to supply the works with limestone and water.

This was closely followed by the incredible and innovative design for a mechanism to pump air into the blast furnaces – a huge timber aqueduct spanning the River Taff and providing water to power a 15m diameter waterwheel, used to work an air pump for blowing the iron smelting furnaces. The Gwynne Aqueduct and ‘Aeolus Waterwheel’ soon became famous throughout the country, and visitors would come to Merthyr just to see them. Indeed Some contemporary accounts actually referred to the Aeolus Wheel as ‘the Eighth Wonder of the World’.

In 1799, George designed what would become his most iconic structure – the Old Iron Bridge, and two years later he designed the Ynysfach Ironworks.

In about 1805, having helped Cyfarthfa Ironworks expand, George left the partnership. Reports vary on the amount of money he amassed for his 13 years of service, either £40,000 or £100,000 — “equal to one share”. He joined Pontypool Ironworks as partner to its owners Capel Hanbury Leigh (1776-1861) and Robert Smith, restructuring the works and making great improvements to balling and refinery operations.

In 1811 he prepared a design for Chepstow Bridge – a series of cast iron spans on the existing piers. His design was not adopted, and the new bridge was eventually designed by John Urpeth Rastrick. George’s designs for the Chepstow bridge are his last known work.

Watkin George died on 10 August 1822 and was buried at St Cadoc’s Church in Trevethin.

Today, of his works, the Ynysfach Ironworks Engine House still stands, and his Pont-y-Cafnau is the oldest surviving example of a cast iron railway (tramway) bridge and aqueduct, and is probably the second oldest surviving iron bridge in the British Isles (after Ironbridge in Shropshire), so he is certainly someone who should be remembered amongst the great men of Merthyr.

Merthyr’s Heritage Plaques: Dr Joseph Parry

by Keith Lewis-Jones

Dr Joseph Parry

Plaque sited at 4 Chapel Row,CF48 1BN

Joseph Parry was born on 24 May 1841 in the front, side room of 4 Chapel Row, Georgetown, Merthyr Tydfil. At the age of seventeen he began to take music lessons and made rapid progress. He sent four compositions to the Swansea Eisteddfod in 1863 signing them ‘Bachgen Bach o Ferthyr, erioed, erioed’ (A Merthyr boy forever and ever).

In 1868 he entered the Royal Academy of Music in London, where he studied for three years.

It is estimated that his songs numbered about 300, including the well-loved ‘Myfanwy’, in addition to some 300 anthems, chorales, glees, choruses, operas and orchestral works. He is probably best known internationally for his hymn tune ‘Aberystwyth’ – ‘Jesu, lover of my soul’.

CONFESSION OF RICHARD EDWARDS.

In the early part of the week, the Culprit made the following statement to the Chaplain:-

“I was not alone when my mother came by her death There were three presents beside me. My child (10 months old), was in bed in the room. My mother died on Thursday night. When dead, two women placed my mother in bed beside my little boy, where the corpse remained until the Monday night following. The two other persons present, beside me and my wife, when my mother died, were the nearest relations of Peggy (my wife). Peggy and the other person had been in the womb of the other. These three persons told my father-in-law and my mother-in-law’s sister, that they had passed that night in Cefn Coed Cymmer. I gave my mother a blow about the jaw, because Peggy cried out that my mother was beating her. My mother fell down under my blow.

Peggy, her mother, and brother then laid hold on my mother. My mother did not speak; she groaned for some time. I saw Peggy and the other two squeezing her throat until she ceased groaning. I was in liquor: the three others were not. This happened about 12 or 1 o’clock, I cannot tell exactly, for there was no clock or watch there. And now, if Peggy had been allowed to be examined by me in the Hall, I would have made all this known then. Peggy asked me to bury her. I said I would not, I would leave her there, for I was afraid to be seen. I told them they had killed my mother. They begged me to keep everything secret. We all remained in the house till the dawn of day. I then went up to Dowlais, and the others returned home (to my father-in-law’s, as they say) and told their story about being at night at Coed y Cymmer.

I met my wife again about six o’clock the evening of the following Monday, at her aunt’s house, at Cae Draw (Jane Phillips’s) and we went together, the child in her arms, to my mother’s house. My wife placed the child in the opposite side of the bed to where my mother’s body was lying. We then together dragged the corpse out, and placed it under the bed. We continued to live in the house dining the rest of the week sleeping five nights in the bed under which the corpse lay! I was full of anxiety all the week, and on Saturday I started off the day my mother’s body was discovered, leaving my wife in my mother’s house. I was absent from Saturday until the following Wednesday, when I was apprehended in the Cast-House at Dyffryn, and wandering about.

I tell the best truth – the truth I should tell in the presence of God, where I shall he next Saturday – to you now. My blow did not kill my mother, for she groaned afterwards. Her death was caused by their meddling and scuffling with her on the ground. I know not exactly ill what manner. I mean Peggy, and her mother, and brother was scuffling with her. Neither of these three charged me at this time with having killed my mother. This is all true as I shall answer to God. I know nothing of the death of any other human being, male or female. If I did, I should confess it now, having gone so far. But I am guilty of every other sin or crime, excepting theft or murder. And now I have no more to say, having told the whole truth, and my heart is already feeling light. I began to feel lighter yesterday, when I determined and promised you to confess everything”.

The mark X of RICHARD EDWARDS.

The whole of the foregoing statement was read over in Welsh by Mr. Stacey, and explained to Richard Edwards, and signed with the mark by him in my presence, this 18th day of July 1842.

JNO. B. WOODS,

Governor of the County Gaol.

The Execution of Dick Tamar – part 1

The following is transcribed from the Cambrian dated 30 July 1842 – 180 years ago today.

In a Second Edition of our last number, we published a report of the Execution and Confession of Richard Edwards, alias Dick Tamar, who at the last Assizes for this County was found guilty of the murder of his mother, Tamar Edwards. We this week republish the same for the information of our distant readers: –

This atrocious Criminal was executed at Cardiff this morning (Saturday). The convict was visited on Friday night by the Rev. Mr. Stacey, who remained with him for several hours. He seemed to be perfectly resigned to his fate, and frequently offered up prayers to the throne of grace for mercy in the last hour. We understand that several of the Dissenting ministers of Cardiff applied for permission to visit the wretched man, but that he declined seeing any spiritual teacher except the Reverend Chaplain, whose incessant endeavors to bring the poor creature to a proper sense of his situation, are beyond all praise.

Tamar slept soundly after the Reverend Chaplain left him. At twelve o’clock be awoke and left his bed. He expressed himself as being perfectly easy, and appeared firm and collected. At an early hour this morning (Saturday) crowds assembled round the goal, which gradually increased to about eleven thousand persons. At the dawn of day, the worthy Chaplain visited Tamar. Shortly before six o’clock, he asked for tea and bread and butter, and smoked a pipe with apparent unconcern. He observed to the Governor about this time that he was in “very good spirits”.

The Sheriff arrived at the goal at half-past seven in the morning. Edwards was then engaged in prayer with the Chaplain. Shortly before eight o’clock the Sheriff, accompanied by the officers of justice, proceeded to the condemned cell, and formally demanded the body of its miserable inhabitant. Having taken leave of the Chaplain, Edwards was placed under the hands of the executioner, who pinioned him in the cell. Dick repeatedly protested his innocence he underwent the terrible operation with remarkable firmness. The mournful procession then moved down the pathway in front of the Governor’s House, the Chaplain reading portions of the Burial Service. The convict did not show any fear, he wept slightly. Assisted by two turnkeys, he mounted the scaffold, on which he stood with the utmost firmness. Just prior to the rope being placed round his neck he said, “Hear me, I have been guilty of every crime except murder and thieving.” The fatal knot was then tied, and the cap drawn over the criminal’s face, not a muscle quivered – the bolt was then withdrawn, and Dick Tamar after one or two struggles ceased to exist. He did not appear to suffer much.

The body of the criminal was suspended for an hour, and then cut down. Several medical gentlemen were present for the purpose of taking a cast from the head.

Thus, died the Merthyr murderer whose name and crimes will be long remembered.

At the convict’s urgent request, the Holy Communion was administered him. On being asked how he felt, he said, “I have confidence, and hold fast in God’s mercy to me.” He frequently repeated the following verses, which he had committed at some previous time, to memory:-

Mae’r dydd bron myned heibio,
Mae’r haul bron myned lawr,
Mae’n amser ninnau’n tynu
Tua thragywyddoldeb mawr.
Mi af o flaen yr Orsedd,
Er dued yw fy lliw,
Pwv wyr na cha’i drugaredd,
Un rhyfedd iawn yw Duw.
O Arglwydd cladd fy meiau
Cyn fy nghladdu i,
Mewn eigion mor o angof
Sydd yn dy gariad di.
Ni alla’i ddim gwynebu,
Dydd y farn sy’ ddod,
Os na fydd claddu beiau
Cyn hynny wedi bod.

The following is a translation of the above:- “The day is nearly gone, the sun is nearly setting, and our time is drawing towards Eternity. I shall go before the judgement seat, though my crimes are so black; and who knows but that I shall obtain mercy, for God is wonderingly gracious. Oh! Lord, bury my sins before I shall be buried in the depths of Thy love; for I cannot face the day of Judgment, which is to come, unless my sins are buried before that lakes place”.

Merthyr in the Tudor Period

In 1540, an English traveller, John Leland, spent some time travelling through Wales. Luckily, he kept an account of his journey, the relevant part about the Merthyr area is transcribed below.

“Merthyr Tydfil is in the commote of Senghenydd Uwch Caiach which is in the cantref of Eweinlwg. To go from east to west in the highest part of Glamorganshire towards the roots of the Black Mountains, is a sixteen mile of wild ground almost all.

Uwch Caiach stretcheth up to Taf by the east bank from Caiach to Morlays Castelle (sic), and two miles upward by north-north-east to Cae Drain, where the boundary is between Upper Monmouthshire, Breconshire and the Uwch Caiach part of Senghenydd.

Morlays Castelle standeth in a good valley of corn and grass and is on the right bank of the Morlays Brook*. This castle is a ruin and belongs to the King. Morlays Brook……comes out of the Breconshire hills, near Upper Monmouthshire and to Morlays Castelle, and about a mile lower in the parish called Merthyr it goeth into the east bank of the Taf.

There is a hill called Cefn Glas**, and stands between Cynon and Taf. This is the boundary between Miscin (sic) and Senghenydd. The ground between Cynon and Pennar is hilly and woody.

The water of the Taf cometh so down from woody hills and often bringeth down such log and trees, that the country would not be able to rebuild the bridges if they were stone, for they are so often broken.”
