One of Merthyr’s most distinctive, yet overlooked bridges is the Rhydycar Canal Bridge.
The Rhydycar Canal Bridge, or more precisely, the Vale of Neath Railway Bridge, was built in approximately 1850 to carry the Vale of Neath Railway over the Glamorganshire Canal. The Canal was the prime artery of trade linking the ironworks of Merthyr Tydfil with their markets via the port of Cardiff throughout the heyday of the iron industry, from the late 18th Century to the mid 19th Century. Construction of the Canal began at Merthyr in 1790, and it was opened in 1794. It was financed primarily by iron industry interests, among whom the Crawshay family of Cyfarthfa Ironworks were the leading shareholders.
With the growth of the railway industry, the importance of the canal began to wane as several companies brought lines into Merthyr. The Vale of Neath Railway Company built a line from Merthyr Tydfil and Aberdare to Neath, chiefly to transport the products of the Merthyr iron industries to the port at Swansea. The line opened in 1851, and at Rhydycar, the two transport hubs intersected with the railway bridge over the canal.
The bridge, which was built on the site of an earlier bridge, is built of coursed rubble sandstone and brick. It is built on the skew, and comprises three arches. The central arch, which spanned the canal, is elliptical with a 5.5 metre span, and a height of 6.7 metres at its apex. This arch is flanked by two smaller arches which accommodated the towpath of the canal. There are also three access arches in each pier of the main arch, leading to the towpaths.
Following the closure of the railway, the bridge gradually fell in to disrepair. In 2009, it was announced that by Merthyr Council that the bridge would be repaired and renovated. The work was intended stabilise a large vertical crack and stonework. They also intended to return it to its historic setting in the canal basin by excavating an area to reveal the buried canal profile and repairing and reinstating the canal walls. However, these plans never came to fruition.
The bridge is now scheduled as a GradeII listed building as a now rare example of one of the early bridges on the important Glamorganshire Canal.
