Briton Ferry Bridge is a crossing on the River Neath, to the east of Swansea on the A48. For many years it formed part of the Briton Ferry gap, between completed sections of the M4; however, it was finally bypassed by a completed M4 in 1993, just to the south.
Briton Ferry Bridge actually comprises two separate viaducts, one over the Neath River, and the other over Briton Ferry dock area. A ferry served the area in Roman times, and a regular ferry service operated in the first half of the 20th century.
The bridges form part of the A48 Neath bypass scheme, designed by Rendel, Palmer & Tritton, a company which is still recognisably present in the UK market as Rendel Ltd, despite mergers and take overs. Construction of the two viaducts began in 1949, and they comprise a 17 span 585m long steel viaduct to the west and a 11 span 296m steel viaduct to the east. The bridges are linked by a short length of dual carriageway over a small hill known as Warren Hill.
The bridges were built from steel on concrete piers by Cleveland Bridge and Engineering Company (another company still in business) and include two 6.7m wide carriageways together with cycle tracks and footways.
The main span on the western bridge is 91.4m in length, and the main girders of this span extend above carriageway level as seen in the Streetview image here: https://goo.gl/maps/y2NP9cNci1N2.
