English: Beneath Barmouth Bridge A view underneath the bridge. Predominately of wooden construction, there was serious concern in the 1980's that the structure was so compromised by marine worm infestation that it would have to be condemned. At that time of minimum investment in railway infrastructure, the estimated cost of repair was seen to be prohibitive and the whole Cambrian Coast line was threatened with closure. Fortunately, a cheaper solution was found and the bridge was saved. In this view the wooden piers can be seen with the concrete reinforcement which saved the structure.
