Demolishing Cefn Railway Bridge

submitted by Carl Llewellyn

While perusing the old Merthyr Expresses I came across an article written on 16 July 1970 entitled:-

Down Comes Link With Railways Pioneers

On 6 July, 1970, Cefn Railway Bridge, which spanned the Cefn Coed High Street was demolished after 104 years due to its unsafe condition. Demolition began at 08:00 a.m. and was completed with about four hours.

The bridge was a continuation of the Cefn Pontycapel Viaduct which completed in 1866 at a cost of £25,000 (equivalent to £2.1 million). The routing of the railway it served, may have been affected by the strong pressure from the powerful Crawshay iron masters.

The viaduct was built by Thomas Savin and John Ward, his brother-in-law, to designs prepared by Alexander Sutherland. It had been described as a graceful and majestic structure, one of the finest viaducts in South Wales, being built on a graceful curve which added much to its beauty. With fifteen arches 40 feet each, it has a total length of 725 feet and a height of 115 feet.

The Viaduct came into being after many trials and tribulations. At the beginning of 1866 a crisis occurred – Thomas Savin who with John had been managing the railway, and had been paying the shareholders their guaranteed five percent, was overwhelmed by his commitments and failed disastrously, nearly bringing down the finances of the Brecon and Merthyr Junction Railway with him. Other legal frays remained a prominent feature of their lives for the following four years. But despite all this the railway was completed.

The saviour of the venture was Alexander Sutherland who produced an alternative route into Merthyr, which avoided Cyfarthfa Castle by going down the West side of the valley and so won the support instead of the emnity of the Crawshay Family. This was achieved at great engineering expense.

It has been said that a bribe was accepted to divert the railway line around the Crawshay property instead of through it.

The six and three-quarter miles between Pontsticill and Merthyr involved a descent at 1 in 45-50 feet and between Morlais Junction and Merthyr and two complete reversals of direction.

At one stage in the construction of the Pontycapel Viaduct, the stone masons went on strike which meant that the bricklayers had to be called in. This is why one sees bricks lining the underneath of the arches while the remainder of the structure is stone.

The last brick was ceremonially laid by Mrs Sutherland in 1866, but there were further interruptions due to contracting difficulties and it was not until 1 August 1867 that the line was opened from Pontsticill to Cefn, which then replaced Pant as the terminus for the Merthyr horse bus.

The word Pontycapel means bridge to the chapel – it did in fact lead over to a chapel although it is believed that there was a Roman Catholic church at Tai-mawr.

Mr Elwyn Bowen, headmaster of Ysgol-y-Graig Junior School and local historian, said he was told by his Uncle, who would have reached the age of some 90 years, that when the footings were being dug for the viaduct a number skeletons were unearthed.
