Menai Suspension Bridge to Close Tomorrow for 200th Anniversary
The Grade I-listed Thomas Telford structure, one of the world's first major suspension bridges, will close from 6am to 2pm on Saturday for the 'Bont Borth 200' festival.
Tomorrow morning, the Menai Suspension Bridge will close for several hours as the island of Anglesey and the mainland mark a milestone few pieces of transport infrastructure ever reach. The Grade I-listed crossing, designed by Thomas Telford and opened on 30 January 1826, celebrates its 200th anniversary this year, and on Saturday 8 August the structure will be closed for parts of the day to mark the bicentenary.
The closure will run from 6am to 2pm, with the bridge fully shut to traffic between 10am and 2pm to accommodate the ‘Bont Borth 200’ festival, commemorating a structure that, when it opened, was one of the world’s first major suspension bridges. The event will celebrate the bridge’s enduring place in engineering history, returning the crossing briefly to a pedestrian experience closer to what Telford’s first travellers would have known.
That a 200-year-old suspension bridge is still carrying traffic at all is a quiet engineering success story. Telford’s design was so robust that the bridge required no major structural intervention for its first century and a half, and even today the most disruptive closures have come from maintenance work on the deck and the hangers rather than any fundamental flaw in the iron chains that give the bridge its distinctive profile. The anniversary closure is a rare planned interruption, not a repair.
The bridge’s opening in 1826 placed it at the very beginning of the suspension bridge era. It was preceded only by a handful of smaller spans, and its 176-metre central span was by far the longest of its kind in the world. The Menai Suspension Bridge effectively demonstrated that a suspended roadway could handle the weight and weather of a busy crossing, and Telford’s work directly influenced the next generation of bridge builders on both sides of the Atlantic.
Celebrating a bicentenary by closing a bridge might seem counterintuitive, but it is also the most direct way to let people experience the structure on foot, just as many did when it first opened. The ‘Bont Borth 200’ festival is expected to draw crowds to both sides of the strait, and the closure will temporarily return the crossing to something closer to its original condition — a connection point for people rather than for the vehicles that normally stream across it.
For a Grade I-listed structure that remains a working link between Anglesey and the Welsh mainland, this planned shutdown is a rare acknowledgement that a piece of infrastructure can be both a vital transport artery and a monument worth celebrating in its own right.
