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.The River Neath Bridge has three steel approach spans on the west side and two on the east.
