The Penmaenbach road tunnel, along the A55 is situated through the heart of an ancient volcano that has been extinct for 450 million years.

Traffic Wales has managed the operation of the Penmaenbach, Pen y Clip and Conwy road tunnels since their construction - a job that requires a trained team to be on duty 24 hours per day, 365 days per year.
