The Old Wye Bridge in Chepstow, a Grade I-listed structure connecting Wales and England, may face renewed closure as concerns mount over its sensitivity to rising temperatures. Engineers have identified cracks in the bridge’s cast iron beams, prompting the initial closure to vehicles last October. In March, authorities extended the closure to pedestrians and cyclists amid safety concerns.

The bridge, notable as the world’s oldest five-arch cast iron bridge, had been reopened to foot traffic ahead of the weekend. However, with forecasts predicting temperatures reaching 28 to 29 degrees Celsius in Chepstow over the coming days, there are indications that the increased heat could exacerbate the existing structural issues. Officials have warned that the bridge may need to be closed again as a precautionary measure.

The structural vulnerability of the bridge underscores challenges in maintaining historic infrastructure amid changing climate patterns. Engineers continue to monitor the bridge closely to assess any further impact from thermal expansion on the fragile cast iron components. No definitive timeline has been given for a permanent solution or reopening to all traffic, as safety remains the priority.
