Thomas Richardson had acquired the Hartlepool Iron Works in 1847 and this bridge lintel is dated 1851. Although it doesnt appear to be structural as the surround bridge is much newer.
A friend at Network Rail informs me there is a 1940 steel deck built from old rails that carries no tracks.
The live line are carried by a modern steel slab deck installed in 1989.
