The viaduct was built to the design of Henry Robinson of Llantysilio, chief engineer to the Shrewsbury to Chester Railway, in 1846, Thomas Brassey being the general contractor, and completed in August 1848. The cost was £72,346. The Shrewsbury Chester line was initiated by 'King' Robinson, who had received his training under George Stephenson, and who recognised the need, not met by the canals, to transport materials to Wrexham and Chester. The line became part of the Great Western Railway system in 1854.


Built of coursed squared rock-faced sandstone, the upper arched stage of brick faced with stone. It is 460m (1,508ft) long, comprising 19 arches of 18.2m (60ft) span, rising 46m (147ft) above the river. The main piers are tapered upwards to the springing line, above which the arch voussoirs are recessed behind the face. Above, the low parapet is carried on a corbel table.
