On 25 June 1976 this was all that remained of Menai Bridge signal box. Originally controlling access to the Caernarfon branch, it was taken out of use when Bangor box took over control of the new single line over the rebuilt Britannia Bridge. Menai Bridge goods yard had been opposite the box; one of the yard buildings is seen in this view.
