The construction of Carreghofa Lane Bridge is part of the next major step forward for the restoration of a four-mile section of the canal between Llanymynech and Maerdy.
Work has begun in mid-June and is expected to take nine months. The existing Carreghofa Lane will remain open during the works with the causeway, which has severed the route of the canal since the 1960s, being removed once the new bridge is in place.
Richard Harrison, principal project manager at Glandŵr Cymru, said: "We have made good early progress in the construction of Carreghofa Lane Bridge. It is another significant step forward in the long-held ambition to restore this historic canal as we look to secure its future for coming generations.
"The new bridge will provide sufficient headroom for boats and those on the towpath to pass underneath, while carrying the modern carriageway above for vehicles. This will enable future navigation on this stretch of the canal – a major step in the efforts to restore the canal.
