A girder Bridge over the river Doethie near Rhandirmwyn.

Girder Bridge across the river Doethie.

Set in the wilds above Rhandirmwyn, the river Doethie is the first tributary to join the river Tywi, giving this girder bridge across the Doethie beneath Craig Clungwyn, the title of being Carmarthenshire's most northerly bridge and another crossing point between Carmarthenshire and Ceredigion.
