Swing Bridge, River Neath

The Neath River Swing Bridge is a swing bridge over the River Neath, in Wales. It carried the former Rhondda and Swansea Bay Railway near Skewen. The bridge was constructed as a result of the Rhondda and Swansea Bay Railway Act of 1892, which aimed to provide access along the length of the river from wharves and jetties down past Briton Ferry. [2]

The River Neath Bridge has three steel approach spans on the west side and two on the east. They are of plate girder construction, and of through type, supported on piers that each consists of a pair of cylindrical columns, either of wrought iron or steel plate, which are connected by horizontal and cross bracing. The total length of the bridge is 388 feet (118 m).

The 180-foot-long opening span (55 m) is pivoted centrally on a pier of six cylindrical columns similar to those that form the piers to the approach spans, but placed in a ring. They are capped by a large cylindrical drum that contains the supporting rails and the operating mechanism. The swinging span is 27 ft wide (8.2 m). [3]

After many years of decline, however, the swing-bridge facility was hardly ever used. In total, it was used 14 times in 1947, three times in 1948, only once in 1949, and once again in 1956. The last operation was only for testing purposes, at the request of the Neath harbour commissioners. In recent times, the bridge suffered vandalism. A serious fire destroyed its dynamos and pumps, evidence of which is still visible in the steelwork.

On 19 March 1985, the British Railways Board proposed to cease operating the swing-bridge over the River Neath, a move that was considered controversial in South Wales. The Board believed that maintaining the fiction of a swing-bridge presented BR with a cost that is no longer justified. [4]

Despite the bridge being welded shut to permanently lock it, with much of the original R&SB railway route now closed, the section incorporating the Neath river crossing still exists, now forming part of a diversionary goods and any passenger traffic routing over the Swansea District Line. As at 2021, the swing bridge had (has) to pass all east-bound coal traffic originating (spasmodically) from Ryan's coal plant at Blaengwrach in the Neath Valley and earlier, Blaenant colliery (now defunct) and still (2021) that of washery coal traffic to & from Onllwyn in the Dulais Valley on the former Neath & Brecon Branch. All such traffic has to travel from those valleys to Jersey Marine South Junction for reversal up the Rhondda & Swansea Bay Branch to Dynevor Junction immediately west of the swing bridge to then transit eastbound. Apart from some track at Court Sart Junction at Briton Ferry, the R&SB line or what is left of it, runs from Dynevor Junction to Burrows Sidings east of Kings Dock Swansea.

The Taff Vale Railway (TVR) was a standard gauge railway in South Wales, built by the Taff Vale Railway Company to serve the iron and coal industries around Merthyr Tydfil and to connect them with docks in Cardiff. It was opened in stages in 1840 and 1841.

Briton Ferry Human settlement in Wales

Briton Ferry is a town and community in the county borough of Neath Port Talbot, Wales. The Welsh name may indicate that the church, llan, is protected from the wind, awel. Alternatively, Sawel may be a derivative of Saul, St Paul's earlier name. He once landed at Briton Ferry. An alternative Welsh name unused today is Rhyd y Brython, a direct translation of Briton Ferry. The Normans referred to the River crossing as La Brittonne and Leland in 1540 as Britanne Fery.

Severn Railway Bridge Former bridge in United Kingdom

The Severn Railway Bridge was a bridge carrying the railway across the River Severn between Sharpness and Lydney in Gloucestershire, England. It was built in the 1870s by the Severn Bridge Railway Company, primarily to carry coal from the Forest of Dean to the docks at Sharpness; it was the furthest-downstream bridge over the Severn until the opening of the Severn road bridge in 1966. When the company got into financial difficulties in 1893, it was taken over jointly by the Great Western Railway and the Midland Railway companies. The bridge continued to be used for freight and passenger services until 1960, and saw temporary extra traffic on the occasions that the Severn Tunnel was closed for engineering work.

River Neath

River Neath is a river in south Wales running south west from the point at which its headwaters arising in the Brecon Beacons National Park converge to its mouth at Baglan Bay below Briton Ferry on the east side of Swansea Bay.

Neath and Tennant Canal Canals in South Wales

The Neath and Tennant Canals are two independent but linked canals in South Wales that are usually regarded as a single canal. The Neath Canal was opened from Glynneath to Melincryddan, to the south of Neath, in 1795 and extended to Giant's Grave in 1799, in order to provide better shipping facilities. With several small later extensions it reached its final destination at Briton Ferry. No traffic figures are available, but it was successful, as dividends of 16 per cent were paid on the shares. The canal was 13.5 miles (21.7 km) long and included 19 locks.

The Vale of Neath Railway (VoNR) was a broad gauge railway company, that built a line from Merthyr Tydfil and Aberdare to Neath, in Wales, chiefly to transport the products of the Merthyr iron industries to ports on Swansea Bay.

The South Wales Mineral Railway was a railway built to serve collieries in the upper Afan Valley, and bring their output to a dock at Briton Ferry, in South Wales. It opened in stages, in 1861 and 1863. It was built on the broad gauge and had steep gradients, including a rope worked incline near Briton Ferry.

The South Wales Railway was a main line railway which opened in stages from 1850, connecting the Great Western Railway from Gloucester to South Wales. It was constructed on the broad gauge. An original aspiration was to reach Fishguard to engender an Irish ferry transit and transatlantic trade, but the latter did not materialise for many years, and never became an important sector of the business. Neyland was the western terminus of the line until 1906.

The Dulas Valley Mineral Railway was incorporated in 1862 to bring coal from the Onllwyn area north-east of Neath to the quays there, and in the following year was reconstituted as the Neath and Brecon Railway. The line was opened as far as Onllwyn in 1863.

The Rhondda and Swansea Bay Railway was a Welsh railway company formed to connect the upper end of the Rhondda Fawr with Swansea, with the chief objective of transporting coal and other minerals to Swansea docks. It was incorporated in 1882, but at first the connection to Swansea from Briton Ferry was refused.

Aberdare Canal canal in Wales

The Aberdare Canal was a canal in Glamorgan, Wales which ran from Aberdare to a junction with the Glamorganshire Canal at Abercynon. It opened in 1812, and served the iron and coal industries for almost 65 years. The arrival of railways in the area did not immediately affect its traffic, but the failure of the iron industry in 1875 and increasing subsidence due to coal mining led to it becoming uneconomic. The Marquess of Bute failed to halt its decline when he took it over in 1885, and in 1900 it was closed on safety grounds. The company continued to operate a tramway until 1944. Most of the route was buried by the construction of the A4059 road in 1923, although a short section at the head of the canal remains in water and is now a nature reserve. The company was wound up in 1955.

River Don Navigation Waterway navigation in South Yorkshire, England

The River Don Navigation was the result of early efforts to make the River Don in South Yorkshire, England, navigable between Fishlake and Sheffield. The Dutch engineer Cornelius Vermuyden had re-routed the mouth of the river in 1626, to improve drainage, and the new works included provision for navigation, but the scheme did not solve the problem of flooding, and the Dutch River was cut in 1635 to link the new channel to Goole. The first Act of Parliament to improve navigation on the river was obtained in 1726, by a group of Cutlers based in Sheffield; the Corporation of Doncaster obtained an Act in the following year for improvements to the lower river. Locks and lock cuts were built, and, by 1751, the river was navigable to Tinsley.

Severn Bridge Railway

The Severn Bridge Railway was a railway company which constructed a railway from Lydney to Sharpness in Gloucestershire, England. It was intended chiefly to give access for minerals in the Forest of Dean to Sharpness Docks, and the company built a long bridge, 1,387 yards (1,268 m) in length, over the River Severn. The line opened in 1879.
