The height of Menai Suspension Bridge’s road deck above water at high tide is approximately 30.5 metres (or 100 feet) at centre span.
Built by Thomas Telford between 1819 and 1826 across the Menai Strait between the Isle of Anglesey and the Welsh mainland, he designed the bridge height to allow for the passage below of sailing ships of the era at full sail.
The two bridge towers are approximately 47 metres (or 154 feet) tall.
