This is a shot of the viaduct at Lower Lydbrook in the Wye Valley, built in the late 1860s on the Ross on Wye to Monmouth line. Unlike the rest of the line, which closed in 1959, this remained open until 1965 as part of a long siding from Ross on Wye to a cable factory (now closed), the remaining buildings of which are behind me. Unlike the surviving railway viaduct at Redbrook, which featured a footpath even when the line was operational, this has been used as a footbridge (the Wye Valley Walk passes over it) only since the line closed.
Once there were eleven (I think) railway viaducts over the Wye between Hereford and Chepstow ... now only three remain: this one, Redbrook and the Tintern Wireworks viaduct. Of these, Lydbrook and Redbrook are both quietly decaying, despite being well used as pedestrian bridges. Soon I should imagine they'll be demolished and replaced with characterless footbridges, and this will be a shame.
