I can indeed remember the traffic lights for the single file system over the Telford Bridge, Hugo. I think that there was a 6d (2.5p) per car toll as well! I can remember queuing from the Penmaenbach tunnels and beyond,(if you had'nt gone over the Sychnant Pass to dodge the traffic, but then you had to come up through Gyffin to join the queue) and when you had finally got over the bridge you had to hope that your luck was in with the level crossings by the old "Maelgwyn" pub in Junction. There was considerably less traffic in those days though, imagine the chaos now!
